The Yale Conference on Pigment Cell Biology, 1973
This issue of the Yale Journal of Biology and Medicine is devoted to the Proceedings of the Conference on Pigment Cell Biology held in New Haven, CT, Jan. 25-28, 1973, initiated by Aaron B. Lerner and co-sponsored by the Department of Dermatology, Yale University, and the Melanoma Foundation. Several investigators at Yale actively study normal and malignant pigment cells, and all of these worke...
متن کاملA review of Biology and clinical use of Mesenchymal stem cell: an immune -modulator progenitor cell
Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...
متن کاملPigment Epithelium-Derived Factor: Chemistry, Structure, Biology, and Applications
Pigment epithelium-derived factor (PEDF) is a multi-functional serpin protein with demonstrable neurotro-phic, antiangiogenic, antitumorigenic, antimetastatic, anti-inflammatory, antioxidative properties among others. PEDF exists naturally in most organs of the human body, and it is released from most cell types as an extracellular diffusible and circulating glycoprotein. It has been studied mo...
متن کاملXI International Pigment Cell Conference
Melasma is an acquired dark-brown to ashen-gray hypermelanosis with mottled patterns and is found in the exposed areas (forehead, malar eminences, upper lip, chin, neck, etc.). Although melasma is believed to be associated with pregnancy, including several other factors such as genetic, racial, endocrine, and nutritional, exposure to sunlight appears to be one of the primary causes of its exace...
متن کاملMolecular biology of pigment cells. Molecular controls in mammalian pigmentation.
Genetic regulation in bacteria, fungi, yeast, and higher plants has been extensively studied, two well-known systems being the lactose (1) and arabinose (2) operons in Escherichia coli. The understanding of the mechanisms by which these systems function has depended heavily upon (a) the ability to obtain cells bearing mutations, thus allowing for genetic analyses of the various complementation ...
