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 ...
Myeloid-derived suppressor cells (MDSC) are a heterogeneous group of immune cells from the myeloid lineage (a family of cells that originate from bone marrow stem cells). MDSCs expand under pathologic conditions such as chronic infection and cancer, as a result of altered haematopoiesis . [ 1 ]
Cancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic disease and one or more biopsy results inconsistent with a tumor cancer.
Stem cells are being explored for use in conservation efforts. Spermatogonial stem cells have been harvested from a rat and placed into a mouse host and fully mature sperm were produced with the ability to produce viable offspring. Currently research is underway to find suitable hosts for the introduction of donor spermatogonial stem cells.
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research.
URJ-UCCS: Undergraduate Research Journal at UCCS [25] riverrun is the student literary and arts journal published annually. They take poetry, fiction, nonfiction, and visual art submissions. riverrun must never be capitalized because it is a reference to the first word of the book Finnegans Wake, which starts in the middle of a sentence. The ...
Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about three people per million members of the population. [1] It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin. [2]
In alternative medicine, cell therapy is defined as the injection of non-human cellular animal material in an attempt to treat illness. [1] Quackwatch labels this as "senseless", since "cells from the organs of one species cannot replace the cells from the organs of other species" and because a number of serious adverse effects have been ...
