Scar healing which heals with a scar. The myofibroblasts make up a high proportion of the fibroblasts proliferating in the postembryonic wound at the onset of healing. In the rat model, for instance, myofibroblasts can constitute up to 70% of the fibroblasts, and is responsible for fibrosis on tissue. Generally, the myofibroblasts disappear from the wound within 30 days, but can stay around in pathological cases in hypertrophy, such as keloids. Myofibroblasts have plasticity and in mice can be transformed into fat cells, instead of scar tissue, via the regeneration of hair follicles. Early and effective treatment of acne scarring can
Spongy tissue problem is particularly common, giving soft, white, 'corky' tissue. Spongy tissue is also a type of animal tissue which contains smooth muscles, fibrous tissues, spaces, veins, and arteries. An example is the corpus spongiosum penis. In bone, the spongy tissue is called cancellous tissue. Spongy tissue Spongy tissue is a type of tissue found both in plants and animals. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll's function is to allow for the interchange of gases (CO2) that are needed for photosynthesis. The spongy
