A subset of human rapidly self-renewing marrow stromal cells preferentially engraft in mice

Abstract: Controversies have arisen as to whether adult stem cells or progenitor cells from bone marrow can engraft into nonhematopoietic tissues in vivo. To resolve some of the controversies, we developed a highly sensitive polymerase chain reactionbased single nucleotide polymorphism (PCR-SNP) assay for competitive engraftment of mixtures of stem/progenitor cells. We used the assay to follow engraftment in immunodeficient mice of subpopulations of the stem/progenitor cells from human bone marrow referred to as either … Show more

“…44,45 Sites in which active neurogenesis occurs in adulthood, such as the hippocampus, subventricular zone and olfactory bulb, are often included in these preferred engraftment sites. 6,[46][47][48] In this respect the results of this study are not surprising. However, the non-proportional engraftment of MSCs in the hippocampus and dentate gyrus suggests a possible preference to these sites in 'depressed' FSL rats.…”

“…However, the non-proportional engraftment of MSCs in the hippocampus and dentate gyrus suggests a possible preference to these sites in 'depressed' FSL rats. As most studies relate MSC migration and engraftment with the expression of chemokine receptors and adhesion molecules, 45,47 it would be interesting to test their role in the engraftment of MSCs in 'depressed' FSL rats in the future.…”

“…A limitation in our study is that our cells are cultivated and their behavior may differ from endogenous BM-MSCs. Notably, a recent study shows that a small subpopulation of bone marrow-adherent cells that are small in size, seen in the colonies of the earliest passages, express high levels of CXCR4, exhibit greater engraftment after systemic infusion (Lee et al, 2006). However, these small cells depend on the larger cells for survival and diminish quickly with successive passages, and they almost disappear in passage 3 (Colter et al, 2001).…”

“…␤-Actin gene was used as an internal control to normalized equal loading of DNA per reaction. Assuming each MSC contains one copy of Y chromosome and 5 pg of DNA per diploid nucleus, the numbers of BM-MSCs in the myocardium below the ligation were determined (Lee et al, 2006). …”

“…MSC can also produce a variety of growth factors, cytokines, chemokines and proteases that are likely to play a role either in their immunomodulatory or in their migratory function [29][30][31]. In this respect, MSC have been shown to express a restricted pattern of chemokine receptors, including CXCR4, allowing them to migrate to tissues upon specific chemotactic triggers [32][33][34][35]. These features are likely to represent the basis for MSC homing to multiple organs where they undergo a program of tissue-specific differentiation [36].…”
