Blood Cell Growth Factors
SUMMARY Growth factors or colony stimulating factors (CSFs)recently became the subject of headlines around the world. Many published articles in the last few years indicate that the CSFs can correct anemia and pancytopenia of the great majority of patients. Recombinant CSFs are available to the many scientific and therapeutic centers in the U.S.A, Europe and Japan these days. Erythrop oieti...
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 کاملXI International Pigment Cell Conference
Pheomelanin is synthesized within melanocytes of hair follicles in mice of appropriate Agouti (a)or Extension (e)locus genic constitution. Alleles at the a-locus program pheomelanogenesis by altering the internal environment of hair follicles whereas alleles at the e locus do so by direct action through the genome of the melanocyte. For example, although transplanted recessive yellow (ele) mela...
متن کاملFibroblast growth factor signalling controls nervous system patterning and pigment cell formation in Ciona intestinalis
During the development of the central nervous system (CNS), combinations of transcription factors and signalling molecules orchestrate patterning, specification and differentiation of neural cell types. In vertebrates, three types of melanin-containing pigment cells, exert a variety of functional roles including visual perception. Here we analysed the mechanisms underlying pigment cell specific...
متن کاملPigment epithelium-derived factor inhibits the growth of human esophageal squamous cell carcinoma by suppressing neovascularization.
INTRODUCTION Neovascularization consists of angiogenesis and vasculogenesis during which bone marrow-derived endothelial progenitor cells (EPCs) are mobilized for blood vessel formation. Pigment epithelium-derived factor (PEDF) is known to be a potent inhibitor of angiogenesis in some solid carcinomas. However, the effects of PEDF on human esophageal squamous cell carcinoma (ESCC) and vasculoge...
