Pluripotent stem cells are cells that have the capacity to self-renew by dividing and to develop into the three primary germ cell layers of the early embryo and therefore into all cells of the ...

Stem-cell research is the area of research that studies the properties of stem cells and their potential use in medicine. As stem cells are the source of all tissues, understanding their ...

In general, chemotherapy medications work by attacking cells or by preventing them from growing and dividing. Cancer cells tend to grow and divide rapidly and uncontrollably, and many chemotherapy ...

Newly discovered brain cells count each bite before sending the order to cease eating a meal. Columbia scientists have found specialized neurons in the brains of mice that order the animals to ...

Malignant pleural mesothelioma (MPM) is an aggressive cancer, associated with poor prognosis. We assessed the feasibility of patient-derived cell cultures to serve as an ex vivo model of MPM.

Neurons are cells in the body that are responsible for transmitting electrical signals through the nervous system. Different types of neurons affect the ability to move, which begins as an impulse, or ...

and allergic contact granuloma was put forward. A biopsy specimen showed a histopathologic picture of a granulomatous skin reaction with epithelioid histiocytes surrounded by a dense infiltrate of ...

The distinction between a uterine leiomyosarcoma (uLMS) and a perivascular epithelioid cell neoplasm (PEComa) can be quite challenging. Here we report a 39-year-old woman who underwent a hysteroscopic ...

A granuloma is a cluster of cells and other tissues that clump together in response to inflammation. They could develop beneath the skin or deep inside the body, such as in the lungs and intestines.

During TB disease progression, the mononuclear inflammatory cell infiltrates which form the central structure of granulomas undergo cellular changes to form epithelioid cells, multinucleated giant ...
