  2. Fibroblast - Wikipedia

    en.wikipedia.org/wiki/Fibroblast

    Fibroblasts can also migrate slowly over substratum as individual cells, again in contrast to epithelial cells. While epithelial cells form the lining of body structures, fibroblasts and related connective tissues sculpt the "bulk" of an organism. The life span of a fibroblast, as measured in chick embryos, is 57 ± 3 days. [4]

  3. Collagen - Wikipedia

    en.wikipedia.org/wiki/Collagen

    Collagen constitutes 1% to 2% of muscle tissue and accounts for 6% of the weight to skeletal muscle. [4] The fibroblast is the most common cell creating collagen in a body. Gelatin, which is used in food and industry, is collagen that was irreversibly hydrolyzed using heat, basic solutions, or weak acids. [5]

  4. Reticular cell - Wikipedia

    en.wikipedia.org/wiki/Reticular_cell

    A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.

  5. Type IV collagen - Wikipedia

    en.wikipedia.org/wiki/Type_IV_collagen

    Lastly, the type IV collagen molecules bind together to form a complex protein network. [3] To summarize, the process of collagen synthesis occurs mainly in the cells of fibroblasts which are specialized cells with the main function of synthesizing collagen. Collagen synthesis occurs both intracellularly and extracellularly. [5]

  6. Connective tissue - Wikipedia

    en.wikipedia.org/wiki/Connective_tissue

    Ground substance is a clear, colorless, and viscous fluid containing glycosaminoglycans and proteoglycans allowing fixation of Collagen fibers in intercellular spaces. Examples of non-fibrous connective tissue include adipose tissue (fat) and blood. Adipose tissue gives "mechanical cushioning" to the body, among other functions.

  7. Dense irregular connective tissue - Wikipedia

    en.wikipedia.org/wiki/Dense_irregular_connective...

    This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. [3] It is also in the sclera and in the deeper skin layers. Due to high portions of collagenous fibers, dense irregular connective tissue provides strength, making the skin resistant to tearing by stretching forces from different directions.

  8. Dense connective tissue - Wikipedia

    en.wikipedia.org/wiki/Dense_connective_tissue

    The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers. Dense connective tissue forms strong, rope-like structures such as tendons and ligaments.

  9. Reticular connective tissue - Wikipedia

    en.wikipedia.org/wiki/Reticular_connective_tissue

    Reticular connective tissue is a type of connective tissue [1] with a network of reticular fibers, made of type III collagen [2] (reticulum = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this tissue type are they dominant. [3] Reticular fibers are synthesized by special fibroblasts called ...
