Keratinocyte cells are found in the deepest basal layer of the stratified epithelium that comprises the epidermis, and are sometimes referred to as basal cells or basal keratinocytes. The main function of fibroblasts is to maintain the structural integrity of connective tissues by continuously secreting precursors of the extracellular matrix. In addition, these protective layers are part of the blood-brain barrier. this image depicts.

The fibroblast synthesizes the collagen and ground substance of the extracellular matrix. E. Aikawa, in Comprehensive Biomaterials, 2011. As mentioned above, during fetal wound healing, increased levels of hyaluronan are present, and in vitro studies indicate that hyaluronan decreases fetal fibroblast proliferation (Mast et al., 1993), although specific hylauronan fragments can induce proliferation of adult fibroblasts … This simple arrangement of tissues also characterizes early embryos. Paneth cells serve an immune function and are found at the base of the crypts. Fibroblasts are the most common cell type of connective tissue. It is important for sensation, protection and thermoregulation.
