Dermal fibroblast by homologous recombination, and redirected these pluripotent cells toward the hematopoietic lineages, and transplanted these engineered cells to a lethally irradiated mice." The animals which received the fibroblast stem cell treatment exhibited increased activity levels, indicating recovery from the disorder. Dermal fibroblast Dermal fibroblasts are cells within the dermis layer of skin which are responsible for generating connective tissue and allowing the skin to recover from injury. Using organelles (particularly the rough endoplasmic reticulum), dermal fibroblasts generate and maintain the connective tissue which unites separate cell layers. Furthermore, these dermal fibroblasts produce the protein molecules including laminin and fibronectin which
Cephalopod dermal structures "Lepidoteuthis grimaldii" are actually dermal cushions with a vacuolate internal structure that are continuous with a similarly vacuolate underlying layer of mantle tissue. Ammonium ions (NH) are present in the mantle of this species at a measured concentration of 172 mM. Structurally very similar (though non-overlapping) dermal cushions are found in "Pholidoteuthis adami". It has been proposed that these two species achieve buoyancy by means of the fluid stored in their vacuolate dermal cushions and upper mantle layer. Given their spongy form, these cushions may also play a secondary protective role. The complex dermal structures of "Pholidoteuthis massyae" may play
