Gene therapies raise difficult legal and ethical questions

New advanced therapies can alleviate or cure chronic diseases. But medical progress raises the question of how rights should be protected and balanced, according to Jessica Almqvist, professor in international law and human ...

Study finds two protein pathways downregulated in postnatal heart

In work published today in Stem Cell Reports, researchers from the University of Minnesota Medical School discovered two signaling pathways that are downregulated in human hearts after birth. These pathways, mitogen-activated ...

Cancer research repurposed to expose age-related blood diseases

Clonal hematopoiesis is a biological process in which a blood stem cell (the population that gives rise to a variety of blood cell types) acquires an advantageous mutation and outgrows neighboring cells. Clonal hematopoiesis ...

Another byproduct of aging: Hypermutations in the brain

Genetic mutations in early development have been implicated in several psychiatric disorders such as autism and schizophrenia, symptoms of which typically manifest during childhood and early adulthood. However, mutations ...

Cellular secrets of ageing unlocked by researchers

New research has uncovered how genetic changes that accumulate slowly in blood stem cells throughout life are likely to be responsible for the dramatic change in blood production after the age of 70.

Somatic cell

Somatic cells are any cells forming the body of an organism, as opposed to germline cells. In mammals, germline cells (also known as "gametes") are the spermatozoa and ova which fuse during fertilization to produce a cell called a zygote, from which the entire mammalian embryo develops. Every other cell type in the mammalian body—apart from the sperm and ova, the cells from which they are made (gametocytes) and undifferentiated stem cells—is a somatic cell: internal organs, skin, bones, blood, and connective tissue are all made up of somatic cells.

The word "somatic" is derived from the Greek word sōma, meaning "body".
