Image Glossary > Fibroblast

A type of cell in loose connective tissue that secretes the protein ingredients of the extracellular matrix.

Many somatic cells have been successfully reprogrammed.  However, fibroblast cells are commonly utilized to create induced pluripotent stem cells because they can be easily extracted from a patient using a safe and non-invasive skin biopsy and are easy to culture in a lab.

Reprogramming Factors In 2006, the Yamanaka lab identified four factors that, when co-transfected and expressed in mouse adult fibroblast cells, caused.... Read More
