The development of treatments using stem cells has drawn the attention of researchers to fat deposits given the fact they represent an almost unlimited reservoir of such cells, which can be accessed through minimally invasive techniques. However, the standardization of these studies has been made difficult because of the controversies of nomenclature regarding the many components of adipose tissue. Despite their distinct and independent structures with different metabolic responses, the terms hypodermis and subcutaneous adipose tissue are many times used as synonyms. However, the correct distinction between these two layers, the knowledge of their behavior and an uniformity of these terminologies are of utmost importance.             Thus, the purpose of this study was to make a bibliographic review on the theme, aiming to show the anatomical, histological and metabolic differences between these two tissues and standardize their nomenclature.

Falciform ligaments in the liver are surrounded by adipose tissue. We investigated the capability of adipose-derived stem cells from human liver falciform ligaments (hLF-ADSCs) to differentiate into hepatic-type cells and confirmed the functional capacity of the cells. Mesenchymal stem cells (MSCs) were isolated from the liver falciform ligament and abdominal subcutaneous adipose tissue in patients undergoing partial hepatectomy for liver disease. Cells were cultivated in MSC culture medium. Properties of MSCs were confirmed by flow cytometry, RT-PCR analysis, immunocytochemistry assays, and multilineage differentiation. Hepatic induction was performed using a three-step differentiation protocol with various growth factors. Morphology, capacity for expansion, and characteristics were similar between hLF-ADSCs and adipose-derived stem cells from human abdominal subcutaneous adipose tissue (hAS-ADSCs). However, hematopoietic– and mesenchymal–epithelial transition (MET)-related surface markers (CD133, CD34, CD45, and E-cadherin) had a higher expression in hLF-ADSCs. The hepatic induction marker genes had a higher expression in hLF-ADSCs on days 7 and 10 after the hepatic induction. Albumin secretion was similar between hLF-ADSCs and hAS-ADSCs at 20 days after the hepatic induction. The hLF-ADSCs had a different pattern of surface marker expression relative to hAS-ADSCs. However, proliferation, multilineage capacity, and hepatic induction were similar between the cell types. Accordingly, it may be a useful source of MSCs for patients with liver disease.

The quantity and accessibility of subcutaneous adipose tissue in humans make it an attractive alternative to bone marrow as a source of adult stem cells for therapeutic purposes. However, before such a cell source substitution can be proposed, the properties of stem cells derived from adipose tissue (ADSC) and bone marrow (BMSC), and their differentiated progeny must be compared in an animal model, such as swine, that adequately simulates the structure and physiology of humans. The objective of this work was to induce adult porcine stem cells isolated from subcutaneous adipose tissue and bone marrow to differentiate in vitro along the adipogenic lineage and to compare their transcript profile properties. ADSC and BMSC were isolated from subcutaneous adipose tissue and femurs of adult pigs, respectively, and differentiated along the adipogenic lineage using specific inducing medium. Cells were incubated up to 4 weeks with medium replaced every 3 days. Histological staining with Oil Red O was performed at 0, 2, 4, 7, 14, 21, 28 days of differentiation (dd) to confirm the adipogenic differentiation. RNA was also extracted at these time points. qPCR was performed on PPARG, DBI, ACSL1, CD36, CEBPA, DGAT2, ADFP, ADIPOQ, SCD. The geometrical mean of GTF2H3, NUBP, and PPP2CB was used as an internal control. Gene expression was analyzed using a mixed model of SAS with repeated time. The adipogenic differentiation of both ADSC and BMSC was confirmed by the Oil Red O positive staining. The relative mRNA abundance of all the genes at dd0 was similar between the ADSC and BMSC. The relative mRNA abundance of most of the genes was also similar between ADSC and BMSC throughout the adipogenic differentiation. ACSL1 and ADIPOQ had analogous expression patterns among the cell types. ACSL1 had relatively large mRNA abundance before differentiation, but ADIPOQ was barely detectable. As a consequence of differentiation, ACSL1 increased in relative mRNA abundance about 10-fold, whereas ADIPOQ mRNA increased about 1000-fold. Temporal expression patterns of SCD, DGAT2, and ADFP were similar. The increase in gene expression was >800% for SCD, >500% for ADFP, and >50 000% for DGAT2 after 7dd. ADSC had significantly higher expression of those genes compared to BMSC at 14 and 28dd. Both ADIPOQ and DGAT2 were almost undetectable prior to differentiation. mRNA expression of CD36 and DBI was similar with a significantly larger increase in expression of ADSC compared with BMSC. Relative mRNA abundance of CEBPA and PPARG was also larger in ADSC compared with BMSC; however, BMSC had a remarkable increase in temporal expression of those genes throughout adipogenic differentiation. These results suggest both cell types can differentiate towards the adipogenic lineage but with quantitatively different gene expression patterns. More investigation is needed before the ADSC can be considered a practical alternative source for stem cells in future human clinical applications. This research was supported by the Illinois Regenerative Medicine Institute.

The quantity and accessibility of subcutaneous adipose tissue in humans make it an attractive alternative to bone marrow as a source of adult stem cells for therapeutic purposes. However, before such a cell source substitution can be proposed, the properties of stem cells derived from adipose (ADSCs) and bone marrow (MSCs) and their differentiated progeny must be compared in an animal model that adequately simulates the structure and physiology of humans. The objective of this work was to induce adult porcine stem cells isolated from subcutaneous adipose tissue and bone marrow to differentiate in vitro along the osteoblastic lineage and to compare their morphological, phenotypic, and genotypic properties. MSCs and ADSCs were isolated respectively from femurs and subcutaneous adipose tissue of adult pigs and cultured in vitro using DMEM supplemented with 10% fetal bovine serum (FBS), 1% penicillin G-streptomycin, and 5.6 mg L–1 amphotericin B. After 3 passages, cells were differentiated along the osteogenic lineage using lineage-specific inducing medium. Osteogenic medium contained 100 nm dexamethasone, 10 mm β-glycerophosphate, and 0.005 mm ascorbic acid-2-phosphate. Osteogenic cultures were incubated for 4 weeks in 95% air and 5% CO2 at 39�C. Spent medium was replaced with fresh medium every 3 days. Histological staining with alkaline phosphatase, Von Kossa, and alizarin red S were performed at 0, 2, 4, 7, 14, 21, and 28 days of differentiation (dd). At the same time points, RNA was extracted. qPCR was performed on COL1A1, BGLAP, SPARC, and SPP1. As internal control, the geometrical mean of GTF2H, NUBP, and PPP2C was used. Relative mRNA abundance between cell types was calculated using 1/efficiencydCT. The osteogenic differentiation of both MSCs and ADScs was confirmed by the organization of the cells in nodules and by alkaline phosphatase-, Von Kossa-, and alizarin red S-positive staining. The percent relative abundance of the 4 genes in both cell types was COL1A1 (ca. 50) > SPARC (ca. 45) > SPP1 (ca. 5) > BGLAP ( < 0.1). Cell types showed similar mRNA abundance for COL1A1 and SPARC while SPP1 and BGLAP were, respectively, 10- and 19-fold higher in MSCs than in ADSCs. All of the genes had the same pattern among tissues during differentiation except for SPP1, which showed a >10-fold increase at 14 v. 0 dd only for MSCs. Adipose-derived stem cells demonstrated a clear osteogenic differentiation and similar expression and pattern of the two osteogenic genes most abundant in MSCs (COL1A1 and SPARC). However, the higher abundance of SPP1 and BGLAP and the different behavior of SPP1 in MSCs suggest a different transcription profile between the two cell types. From these preliminary results, adipose tissue can be a practical alternative source for stem cells in future human clinical applications.
