(1) In vitro, bone marrow-derived stromal cells (BMSCs) demonstrate inter-donor phenotypic variability, which presents challenges for the development of regenerative therapies. Here, we investigated whether the frequency of putative BMSC sub-populations within the freshly isolated mononuclear cell fraction of bone marrow is phenotypically predictive for the in vitro derived stromal cell culture. (2) Vertebral body, iliac crest, and femoral head bone marrow were acquired from 33 patients (10 female and 23 male, age range 14–91). BMSC sub-populations were identified within freshly isolated mononuclear cell fractions based on cell-surface marker profiles. Stromal cells were expanded in monolayer on tissue culture plastic. Phenotypic assessment of in vitro derived cell cultures was performed by examining growth kinetics, chondrogenic, osteogenic, and adipogenic differentiation. (3) Gender, donor age, and anatomical site were neither predictive for the total yield nor the population doubling time of in vitro derived BMSC cultures. The abundance of freshly isolated progenitor sub-populations (CD45−CD34−CD73+, CD45−CD34−CD146+, NG2+CD146+) was not phenotypically predictive of derived stromal cell cultures in terms of growth kinetics nor plasticity. BMSCs derived from iliac crest and vertebral body bone marrow were more responsive to chondrogenic induction, forming superior cartilaginous tissue in vitro, compared to those isolated from femoral head. (4) The identification of discrete progenitor populations in bone marrow by current cell-surface marker profiling is not predictive for subsequently derived in vitro BMSC cultures. Overall, the iliac crest and the vertebral body offer a more reliable tissue source of stromal progenitor cells for cartilage repair strategies compared to femoral head.

The tumor microenvironment can profoundly affect tumor cell survival as well as alter antitumor drug activity. However, conventional anticancer drug screening typically is performed in the absence of stromal cells. Here, we analyzed survival of myeloma cells co-cultured with bone marrow stromal cells (BMSC) using an automated fluorescence microscope platform, ScanR. By staining the cell nuclei with DRAQ5, we could distinguish between BMSC and myeloma cells, based on their staining intensity and nuclear shape. Using the apoptotic marker YO-PRO-1, the effects of drug treatment on the viability of the myeloma cells in the presence of stromal cells could be measured. The method does not require cell staining before incubation with drugs, and less than 5000 cells are required per condition. The method can be used for large-scale screening of anticancer drugs on primary myeloma cells. This study shows the importance of stromal cell support for primary myeloma cell survival in vitro, as half of the cell samples had a marked increase in their viability when cultured in the presence of BMSC. Stromal cell–induced protection against common myeloma drugs is also observed with this method.

Abstract Hemopoiesis in long-term bone marrow cultures (LTBMC) is dependent on adherent stromal cells that form an in vitro hemopoietic microenvironment. Myeloid bone marrow cultures (MBMC) are optimal for myelopoiesis, while lymphoid bone marrow cultures (LBMC) only support B lymphopoiesis. The experiments reported here have made a comparative analysis of the two cultures to determine whether the stromal cells that establish in vitro are restricted to the support of myelopoiesis or lymphopoiesis, respectively, and to examine how the different culture conditions affect stromal cell physiology. In order to facilitate this analysis, purified populations of MBMC and LBMC stroma were prepared by treating the LTBMC with the antibiotic mycophenolic acid; this results in the elimination of hemopoietic cells while retaining purified populations of functional stroma. Stromal cell cultures prepared and maintained under MBMC conditions secreted myeloid growth factors that stimulated the growth of granulocyte-macrophage colonies, while no such activity was detected from purified LBMC stromal cultures. However, this was not due to the inability of LBMC stroma to mediate this function. Transfer of LBMC stromal cultures to MBMC conditions resulted in an induction of myeloid growth factor secretion. When seeded under these conditions with stromal cell- depleted populations of hemopoietic cells, obtained by passing marrow through nylon wool columns, the LBMC stromal cells could support long- term myelopoiesis. Conversely, transfer of MBMC stroma to LBMC conditions resulted in a cessation of myeloid growth factor secretion; on seeding these cultures with nylon wool-passed marrow, B lymphopoiesis, but not myelopoiesis, initiated. These findings indicate that the stroma in the different LTBMC are not restricted in their hemopoietic support capacity but are sensitive to culture conditions in a manner that may affect the type of microenvironment formed.

Abstract Abstract 2581 The bone marrow (BM) microenvironment consists of a heterogeneous population including mesenchymal stem cells and as well as more differentiated cells like osteoblast and adipocytes. These cells are believed to be crucial regulators of hematopoetic cell development, however, so far, their identity and specific functions has not been well defined. We have by using Ebf2 reporter transgenic Tg(Ebf2-Gfp) mice found that CD45−TER119−EBF2+ cells are selectively expressed in non-hematopoietic cells in mouse BM and highly enriched with MSCs whereas the EBF2− stromal cells are very heterogenous (Qian, et al., manuscript, 2010). In the present study, we have subfractionated the EBF2− stromal cells by fluorescent activated cell sorter (FACS) using CD44. On contrary to previous findings on cultured MSCs, we found that the freshly isolated CD45−TER119−EBF2+ MSCs were absent for CD44 whereas around 40% of the CD45−TER119−EBF2− cells express CD44. Colony forming unit-fibroblast (CFU-F) assay revealed that among the CD45−LIN−EBF2− cells, CD44− cells contained generated 20-fold more CFU-Fs (1/140) than the CD44+ cells. The EBF2−CD44− cells could be grown sustainably in vitro while the CD44+ cells could not, suggesting that Cd44− cells represents a more primitive cell population. In agreement with this, global gene expression analysis revealed that the CD44− cells, but not in the CD44+ cells expressed a set of genes including connective tissue growth factor (Ctgf), collagen type I (Col1a1), NOV and Runx2 and Necdin(Ndn) known to mark MSCs (Djouad et al., 2007) (Tanabe et al., 2008). Furthermore, microarray data and Q-PCR analysis from two independent experiments revealed a dramatic downregulation of cell cycle genes including Cdc6, Cdca7,-8 and Ki67, Cdk4-6) and up-regulation of Cdkis such as p57 and p21 in the EBF2−CD44− cells, compared to the CD44+ cells indicating a relatively quiescent state of the CD44− cells ex vivo. This was confirmed by FACS analysis of KI67 staining. Furthermore, our microarray analysis suggested high expression of a set of hematopoietic growth factors and cytokines genes including Angiopoietin like 1, Kit ligand, Cxcl12 and Jag-1 in the EBF2−CD44− stromal cells in comparison with that in the EBF2+ or EBF2−CD44+ cell fractions, indicating a potential role of the EBF2− cells in hematopoiesis. The hematopoiesis supporting activity of the different stromal cell fractions were tested by in vitro hematopoietic stem and progenitor assays- cobblestone area forming cells (CAFC) and colony forming unit in culture (CFU-C). We found an increased numbers of CAFCs and CFU-Cs from hematopoietic stem and progenitor cells (Lineage−SCA1+KIT+) in culture with feeder layer of the EBF2−CD44− cells, compared to that in culture with previously defined EBF2+ MSCs (Qian, et al., manuscript, 2010), confirming a high capacity of the EBF2−CD44− cells to support hematopoietic stem and progenitor cell activities. Since the EBF2+ cells display a much higher CFU-F cloning frequency (1/6) than the CD44−EBF2− cells, this would also indicate that MSCs might not be the most critical regulators of HSC activity. Taken together, we have identified three functionally and molecularly distinct cell populations by using CD44 and transgenic EBF2 expression and provided clear evidence of that primary mesenchymal stem and progenitor cells reside in the CD44− cell fraction in mouse BM. The findings provide new evidence for biological and molecular features of primary stromal cell subsets and important basis for future identification of stage-specific cellular and molecular interaction pathways between hematopoietic cells and their cellular niche components.

Mucin-like molecules represent an emerging family of cell surface glycoproteins expressed by cells of the hematopoietic system. We report the isolation of a cDNA clone that encodes a novel transmembrane isoform of the mucin-like glycoprotein MGC-24, expressed by both hematopoietic progenitor cells and elements of the bone marrow (BM) stroma. This molecule was clustered as CD164 at the recent workshop on human leukocyte differentiation antigens. CD164 was identified using a retroviral expression cloning strategy and two novel monoclonal antibody (MoAb) reagents, 103B2/9E10 and 105.A5. Both antibodies detected CD164/MGC-24v protein expression by BM stroma and subpopulations of the CD34+ cells, which include the majority of clonogenic myeloid (colony-forming unit–granulocyte-macrophage [CFU-GM]) and erythroid (blast-forming unit-erythroid [BFU-E]) progenitors and the hierarchically more primitive precursors (pre-CFU). Biochemical and functional characterization of CD164 showed that this protein represents a homodimeric molecule of approximately 160 kD. Functional studies demonstrate a role for CD164 in the adhesion of hematopoietic progenitor cells to BM stromal cells in vitro. Moreover, antibody ligation of CD164 on primitive hematopoietic progenitor cells characterized by the cell surface phenotype CD34BRIGHTCD38− results in the decreased recruitment of these cells into cell cycle, suggesting that CD164 represents a potent signaling molecule with the capacity to suppress hematopoietic cell proliferation. © 1998 by The American Society of Hematology.

The bone marrow (BM) is well known to be the major site of Ig production in secondary immune responses; thus, the microenvironment of BM is considered to be essential for final differentiation of plasma cells. We identified in the peripheral blood (PB) early plasma cells (CD38++CD19+VLA-5-) committed to entering the BM. The sorted early plasma cells rapidly entered apoptosis in vitro, but these cells could survive and further differentiate into mature plasma cells (CD38 CD19+) just as BM plasma cells in the presence of a BM-derived stromal cell line (KM-102). Culture supernatants of KM-102 cell lines could also support survival of these cells, and antibody to interleukin-6 (IL-6) completely blocked the effect of these supernatants. Furthermore, recombinant IL-6, but not IL-1 or IL-3, could support their survival and their differentiation into mature plasma cells (CD38 CD19+VLA-5+) with expression of VLA-5 mRNA. Therefore, here is direct evidence that early plasma cells found in the PB differentiated into mature plasma cells with stromal cell-derived IL-6 in vitro; thus, BM stromal cells control the final checkpoint of plasma cell differentiation with secretion of IL-6 in the BM.

Abstract The effects of a novel cytokine FLK2/FLT3 ligand (FL) on human fetal bone marrow-derived CD34+CD19+ pro-B cells were analyzed in a stromal- cell-independent, serum-deprived culture system. FL, like interleukin-3 (IL-3), synergized with IL-7 in promoting pro-B cell growth, and differentiation of these cells into CD34-CD19+clgM+slgM- pre-B cells, whereas a small proportion of these cells even differentiate into more mature slgM+ B cells. In contrast, KIT ligand (KL) and granulocyte- macrophage colony-stimulating factor (GM-CSF) were ineffective in promoting IL-7-dependent pro-B cell growth and differentiation. Maximal levels of pro-B cell expansion, generally resulting in 15- to 30-fold increases in cellularity, were obtained in cultures supplemented with optimal doses of FL + IL-7 + IL-3. The addition of mouse bone marrow stromal cells further enhanced the proliferation and differentiation of pro-B cells obtained in the presence of these three cytokines. Under these conditions, cultures could be maintained for more than 4 weeks, and in general 40- to 50-fold increases in cell numbers were observed by 3 weeks of culture. The percentages of clgM+ and slgM+ B cells increased 1.5- to 3-fold and 2-fold, respectively, suggesting that stromal cells may provide additional costimulatory signals for human B- cell growth and differentiation that are different from IL-7, IL-3, and FL. Collectively, our results indicate that FL, in contrast to KL, strongly promotes long-term expansion and differentiation of human pro- B cells in the presence of IL-7 or in combination of IL-7 and IL-3, which is a novel property of this hematopoietic growth factor.
