Screening for recurrently mutated genes in the mononuclear cell fraction revealed mutations in SF3B1 in 39 of 40 cases (97.5%), combined with TET2 and DNMT3A in 11 (28%) and 6 (15%) patients, respectively. (nih.gov)
Scientists have long had the tools to identify the genes being transcribed in a single cell. (acs.org)
Many recently discovered genes that perturb HSC quiescence disrupt stem cell maintenance and homeostatic blood cell production also. (abic2004.org)
Cells become cancerous by accumulating, stepwise, a series of several mutations that alter the function of genes important for cell growth. (agemed.org)
Found within Wharton's jelly - which is easily harvested from what would otherwise be post-natal medical waste - are several distinct stem cell genes. (articlecity.com)

Objective: the aim of this study was to conduct a literature review of the types of stem cells of dental origin and their applications in Dentistry. (bvsalud.org)

Mesenchymal Stem Cells Instruction Manual Product Description Mesenchymal Stem Cells (MSC), also termed Mesenchymal Stromal Cells, are self-renewing multipotent cells that can differentiate into a wide variety of cell types. (tomeipowered.com)

The biological activity of automatically isolated CD133 + cells was evaluated and compared to manually isolated CD133 + cells via functional assays as well as immunofluorescence microscopy. (biomedcentral.com)
For decades, hematopoietic stem and progenitor cells have been studied primarily through such transplantation-based assays. (digs-bb.de)
