AbstractBone marrow-derived mesenchymal stem cells (BM-MSCs) are multipotent stromal cells, which have a critical role in the maintenance of skeletal tissues such as bone, cartilage, and the fat found in bone marrow. In addition to providing microenvironmental support for hematopoietic processes, BM-MSCs can differentiate into various mesodermal lineages including osteoblast/osteocyte, chondrocyte, and adipocyte cells that are crucial for bone metabolism. While BM-MSCs have high cell-to-cell heterogeneity in gene expression, the cell subtypes that contribute to this heterogeneity in vivo in humans have not been characterized. To investigate the transcriptional diversity of BM-MSCs, we applied single-cell RNA sequencing (scRNA-seq) on freshly isolated CD271+ BM-derived mononuclear cells (BM-MNCs) from two human subjects. We successfully identified LEPRhiCD45low BM-MSCs within the CD271+ BM-MNC population, and further codified the BM-MSCs into distinct subpopulations corresponding to the osteogenic, chondrogenic, and adipogenic differentiation trajectories, as well as terminal-stage quiescent cells. Biological functional annotations of transcriptomes suggest that osteoblast precursors may induce angiogenesis coupled with osteogenesis, and chondrocyte precursors may have the potential to differentiate into myocytes. We discovered transcripts for several cluster of differentiation (CD) markers that were highly expressed (e.g., CD167b, CD91, CD130 and CD118) or absent (e.g., CD74, CD217, CD148 and CD68) in BM-MSCs and could be novel markers for human BM-MSC purification. This study is the first systematic in vivo dissection of human BM-MSCs cell subtypes at the single-cell resolution, revealing insight into the extent of their cellular heterogeneity and bone homeostasis.

Marrow Mesenchymal Stem Cells

Abnormal gene expression is frequently observed in nuclear transfer (NT) embryos and is one of the suggested causes of the low success rates of this approach. Recent study has suggested that adult stem cells may be better donor cells for NT, as their less differentiated state may ease epigenetic reprogramming by the oocyte (Kato et al. 2004 Biol. Reprod. 70, 415-418). In the present study, we investigated the expression profile of some selected genes involved in the development of the pre-implantation embryos of in vivo- and NT-derived origin using bone marrow mesenchymal stem cells (MSCs) and porcine fetal fibroblasts (pFF) as donors. Isolated population of MSCs from porcine bone marrow were characterized by cell-surface antigen profile (CD13pos, CD105pos, CD45neg, and CD133neg) and by their extensive consistent differentiation to multiple mesenchymal lineages (adipocytic, osteocytic and chondrocytic) under controlled in vitro conditions (Pittenger et al. 1999 Science 284, 143-147). Primary cultures of pFF from a female fetus at <30 days of gestation were established. for NT, donor cells at 3-4 passages were employed. Embryos cloned from MSCs showed enhanced developmental potential compared to pFF cloned embryos, indicated by higher rates of blastocyst formation (15.3% � 4.8 and 9.0% � 3.9, respectively) and total cell number (31.5 � 7.2 and 20.5 � 5.4, respectively) in Day 7 blastocysts. Total RNA was extracted from pools (triplicates) of 10 embryos each of 8-cell, morula, and blastocyst stages of in vivo and NT origin using Dynabeads� mRNA DIRECT" kit (Dynal, Oslo, Norway). Reverse transcription was performed with a Superscript" III cDNA synthesis kit (Invitrogen, Carlsbad, CA, USA). Real-time PCR was performed on a Light cycler� using FastStart DNA Master SYBR Green I (Roche Diagnostics, Mannheim, Germany). The expression profiles of genes involved in transcription (Oct-4, Stat3), DNA methylation (Dnmt1), de novo methylation (Dnmt3a), histone deacetylation (Hdac2), anti-apoptosis (Bcl-xL), and embryonic growth (Igf2r) were determined. The mRNA of H2a was employed to normalize the levels. Significant differences (P < 0.05) in the relative abundance of Stat3, Dnmt1, Dnmt3a, Bcl2, and Igf2r were observed in pFF NT embryos compared with in vivo-produced embryos, whereas embryos derived from MSCs showed expression patterns similar to those of in vivo-produced embryos. However, Oct-4 and Hdac2 revealed similar expression profiles in NT- and in vivo-produced embryos. These results indicate that MSC-derived NT embryos had enhanced embryonic development and their gene expression pattern more closely resembled that of in vivo-produced embryos. Hence, less differentiated MSCs may have a more flexible potential in improving the efficiency of the porcine NT technique.
