The induced differentiation of mouse ectoderm to epidermis by growth on freeze-thawed dermis
نویسنده
چکیده
Previous investigators have grown or maintained adult or embryonic skin in tissue culture and on the chorioallantoic membrane (CAM) of chickens. These studies have revealed two important factors involved in culturing skin: ( 1) the presence of an inducer which originates in the dermis and affects the phenotype of epithelial cells; and (2} the influence of ·~he physical surface of the substrate on which epidermis is cultured. The current investigation presents evidence that ectoderm from the hmb buds of 10 to 12 day-old mouse embryos can form an epidermis when combined with dermis killed by alternate freezing and thawing, and cultured on the chorio-allantoic membrane of chick embryos. The possible effects that the inducer, physical substrate, and experimental treatment have on the graft material are discuss ed.

Healing Potential of Mesenchymal Stem Cells Cultured on a Collagen-Based Scaffold for Skin Regeneration
Background: Wound healing of burned skin remains a major goal in public health. Previous reports showed that the bone marrow stem cells were potent in keratinization and vascularization of full thickness skin wounds. Methods: In this study, mesenchymal stem cells were derived from rat adipose tissues and characterized by flowcytometry. Staining methods were used to evaluate their differentiatio...
متن کاملFormation and Origin of Basal Lamina and Anchoring Fibrils in Adult Human Skin
The purpose of this investigation was to study the formation and origin of basal lamina and anchoring fibrils in adult human skin. Epidermis and dermis were separated by "cold trypsinization." Viable epidermis and viable, inverted dermis were recombined and grafted to the chorioallantoic membrane of embryonated chicken eggs for varying periods up to 10 days. Basal lamina and anchoring fibrils w...
متن کاملFate and plasticity of the epidermis in response to congenital activation of BRAF
Germline and somatic mutations in RAS and its downstream effectors are found in several congenital conditions affecting the skin. Here we demonstrate that activation of BRAF in the embryonic mouse ectoderm triggers both craniofacial and skin defects, including hyperproliferation, loss of spinous and granular keratinocyte differentiation, and cleft palate. RNA sequencing of the epidermis confirm...
متن کاملP-128: Fibroblast Growth Factor Improves Oocyte Maturation in Vitrified-Thawed Mouse Follicles
Background: The fibroblast growth factors (FGF-4) are a group of heparin-binding single chain polypeptides that play a pivotal role in development, cell growth, tissue repairing and transformation. The aim of this study is to improve development and maturation outcome of vitrified mouse pre-antral follicle by adding of fibroblast growth factor (FGF) into medium culture. Materials and Methods: P...
