The presence of CD34 on non-hematopoietic cells in various tissues has been linked to progenitor and adult stem cell phenotypes. [ 12 ] It is important to mention that Long-Term Haematopoietic Stem Cells (LT-HSCs) in mice and humans are the haematopoietic cells with the greatest self-renewal capacity and were shown to be CD34 + and CD38 − ...
The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...
The James Cancer Hospital and Solove Research Institute. The Arthur G James Cancer Hospital and Richard J. Solove Research Institute is a dedicated cancer hospital and research center that is part of the university's Comprehensive Cancer Center, with a governance structure separate from, but coordinated with, Ohio State Wexner Medical Center ...
Traditional purification method used to yield a reasonable purity level of mouse hematopoietic stem cells, in general, requires a large (~10–12) battery of markers, most of which were surrogate markers with little functional significance, and thus partial overlap with the stem cell populations and sometimes other closely related cells that ...
Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [16] [17] [13] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin).
Cancer stem cells in breast tumors were first discovered in 2003. [6] There are different theories exist on the origins of these cells. There are findings that indicates that normal cells undergo mutations which result in their transformation into BCSCs, [7] while there are also studies which concluded that these cells come from the misplacement of somatic stem cells de novo.
In addition, variations in CD44 are reported as cell surface markers for some breast and prostate cancer stem cells. In breast cancer research CD44+/CD24- expression is commonly used as a marker for breast CSCs and is used to sort breast cancer cells into a population enriched in cells with stem-like characteristics [22] and has been seen as an ...
Stem cell markers are genes and their protein products used by scientists to isolate and identify stem cells.Stem cells can also be identified by functional assays. Below is a list of genes/protein products that can be used to identify various types of stem cells, or functional assays that do the same. [1]
