Abstract (original English)
Aim To investigate the origin of hematopoietic progenitors contained in the stromal vascular fraction (SVF) of human adipose tissue. Methods Tissue samples obtained from lipectomies were subjected to enzymatic digestion with collagenase to obtain a single-cell suspension. The centrifuged cell pellet, termed SVF, was separated immunomagnetically into CD45(+) and CD45(-) cells and cultured in serum-free medium containing hematopoietic cytokines. The freshly isolated and cultured cells were evaluated to determine their ability to form hematopoietic colony-forming units in clonogenic assays and for the expression of certain hematopoietic transcription factors by reverse transcription-polymerase chain reaction; the gene expression level was compared to that in CD34(+) hematopoietic progenitor cells from cord blood (CB) and adult peripheral blood (PB). To characterize erythroid progenitors, burst-forming units-erythroid (BFU-E) were developed in a semisolid medium under different culture conditions, and the hemoglobin composition and globin gene expression in the erythroid colonies were determined. Results The transcription factors SCL/TAL1, RUNX1, RUNX2 and GATA2 were expressed in both the CD45(+) and CD45(-) SVF populations; however, in contrast to our observations in the CD34(+) cells from CB and adult PB, GATA1 was not detected. Nevertheless, GATA1 could be detected in the SVF ce
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
