Factors that control recruitment of theca cells from ovarian stromal-interstitial cells are important for early follicle development in the ovary. During recruitment, theca cells organize into distinct layers around early developing follicles and establish essential cell-cell interactions with granulosa cells. Recruitment of theca cells from ovarian stromal stem cells is proposed to involve cel...
conclusions according to the results of the present study, it can be concluded that adipose derived mscs can be cultured in serum-free media with no change in their differentiating capacity. this finding gives us a hope for future cell therapy studies and trials with little concern about zoonotic infections or immunological reaction. results the isolated cells showed adherent spindle shaped mor...
Self-renewal and differentiation of B-cell precursors is dependent on interactions with bone marrow (BM) stromal cells and associated extracellular matrix. We have recently developed an interleukin (IL)-7-dependent, BM-derived stromal cell culture that supports the growth of normal human B-cell precursors. In the current study, we have characterized the constitutive expression, cytokine-regulat...
Bioprinting In article 2203021 by Carlos Mota and co-workers, a polysaccharide-based hydrogel human mesenchymal stromal cell spheroids are combined to obtain bioink. Using the spheroid-based bioink, contructs were bioprinted successfully differentiated post-bioprinting cartilagelike tissues.
A recommendation of: Audrey Quéméner, Frédéric Dessauge, Marie-Hélène Perruchot, Nathalie Le Floc’h, Isabelle Louveau The impact of housing conditions on porcine mesenchymal stromal/stem cell populations differ between adipose tissue and skeletal muscle https://doi.org/10.1101/2021.06.08.447546
Protective circulating Abs originate primarily from long-lived plasma cells in the bone marrow. However, the molecular and cellular basis of plasma cell longevity is unknown. We investigated the capacity of primary bone marrow-derived stromal cells to maintain plasma cell viability in vitro. Plasma cells purified from the bone marrow or lymph nodes died rapidly when plated in media, but a subpo...
True macromastia is a rare but disabling condition characterized by massive breast growth. The aetiology and pathogenic mechanisms for this disorder remain largely unexplored because of the lack of in vivo or in vitro models. Previous studies suggested that regulation of epithelial cell growth and development by oestrogen was dependent on paracrine growth factors from the stroma. In this study,...
We dissected the functions of the microenvironment of bone marrow (BM) and fetal liver (FL) at the cellular level by cloning individual stromal calls and characterizing their phenotypical and functional features. Stromal cell clones derived from FL are large in size (mean forward light scatter intensity [mFSC] of 450), express the surface antigen Thy-1 but not Sca-1 and 6 out of 6 are able to d...
Interactions between B cell progenitors and bone marrow stromal cells are essential for normal B cell differentiation. We have previously shown that an immune developmental synapse is formed between human pre-B and stromal cells in vitro, leading to the initiation of signal transduction from the pre-BCR. This process relies on the direct interaction between the pre-BCR and the stromal cell-deri...
The mechanism of cell complex formation between lymphocytes and stromal cells was investigated. We found that lymphoid lines of both T and B lineages could form cell complexes with stromal cells from the thymus as well as bone marrow but not with macrophages or typical fibroblast lines. Formation of these cell complexes is temperature dependent and requires the presence of Mg2+, active cellular...
