A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [1] In humans and other vertebrates there are three types: ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Myogenin is a muscle-specific basic-helix-loop-helix (bHLH) transcription factor involved in the coordination of skeletal muscle development or myogenesis and repair. Myogenin is a member of the MyoD family of transcription factors, which also includes MyoD, Myf5, and MRF4. In mice, myogenin is essential for the development of functional ...
Disease and virology studies can use permanent cells to maintain cell count and accurately quantify the effects of vaccines. [1] Some embryology studies also use permanent cells to avoid harvesting embryonic cells from pregnant animals; since the cells are permanent, they may be harvested at a later age when an animal is fully developed.

Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth. [7] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. [8] [9] Myostatin is assembled and produced in skeletal muscle before it is released into the blood stream. [10]
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
Mural cells were described for the first time in the late 19th century as contractile cells lining up around the endothelium. In reality, it was a variety of cells that had been observed and bundled up under the common name of Rouget cells. Later studies brought controversy about their contractility, and this remains an elusive point today. [4]
Myoglobin is found in Type I muscle, Type II A, and Type II B; although many older texts describe myoglobin as not found in smooth muscle, this has proved erroneous: there is also myoglobin in smooth muscle cells. [14] Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystallography. [15]
