An X-irradiated newt limb is able to regenerate if non-irradiated skin as well as non-irradiated muscle is transplanted to the stump. Non-irradiated epidermis is brought to the stump with a skin graft but not with a muscle graft. In order to know whether limb regeneration required healthy epidermis or not, a triploid skin cuff was set at the most proximal level of an irradiated limb and muscle ...

Osteoporosis increases the risk of bone fracture by reducing mass and thereby increasing fragility. The addition strontium (Sr) nanoparticles in tissue results a strengthening bone, induction formation osteoblasts, reduction reabsorption osteoclasts. use Sr for regeneration has gained significant research interest recent years due to its beneficial properties treating osteoporotic-induced loss....

Forearm skin of Stage XXIV Rana pipiens, which cannot regenerate limbs, was removed and placed upon the skinned forearms of young axolotls. The axolotl limbs were amputated immediately through the level of the grafts. Frog epidermis migrated to cover the amputation surface. Dedifferentiation and early blastema formation occurred beneath the frog wound epidermis. Limb regeneration continued, but...

Skin of 14-day icjic and + / + embryos was separated into dermal and epidermal layers using trypsin, and recombined in the combinations + /+ epidermis with + /+ dermis, +/ + epidermis with icfic dermis, icjic epidermis with + /+ dermis, and icjic epidermis with ic/ic dermis. The recombined tissues were implanted in adult histocompatible testes and allowed to grow for 2 weeks. The type of hair t...

Providing a permeability barrier, which prevents both the loss of water and electrolytes and the invasion of pathogens, the skin has a primary protective function. Intact skin is resistant to colonization and invasion of bacteria via a number of mechanisms. The outermost layer of the epidermis, the stratum corneum, constitutes the principal barrier against infection. The stratum corneum consist...
