Many cells bind to components of the extracellular matrix. This cell-to-ECM adhesion is regulated by specific cell surfacecellular adhesion molecules (CAM) known as integrins. Integrins are cell surface proteins that bind cells to ECM structures, such as fibronectin and laminin, and also to integrin proteins on the surface of other cells.
Fibronectins bind to ECM macromolecules and facilitate their binding to transmembrane integrins. The attachment of fibronectin to the extracellular domain initiates intracellular signaling pathways as well as association with the cellular cytoskeleton via a set of adaptor molecules such as actin.[2]

Skin cells are attached to the extracellular matrix by a. anchoring junctions. b. tight junctions. c. plasmodesmata. d. communicating junctions. e. basal bodies.?
c
Sto cell line?
Feeder skin fibroblast cells used to provide the extra-cellular matrix for stem cells.
Where are the mesenchymal cells found?
There are different forms of mesenchymal cells and tissues found almost everywhere in the body, and these tissues can be thought of, broadly, as: connective tissues, blood vessels, and lymphatic vessels.Mesenchymal cells/ tissues originate from the middle embryonic germ layer (there are 3 - endoderm, mesoderm, ectoderm) called the "mesoderm" and differentiate into the body's various connective tissues found in bone, cartilage, ligaments, tendons, muscles, skin, organs, extracellular matrix, as they also form the blood vessels and lymphatic vessels.
Why are skin cells flat?
skin cells are flat, because they are skin cells . your skin is flat right ,so that's why skin cells are flat.
How is cheek cells similar to skin cells?
The cheek cells and skin cells are similar becuase they both are cells they are on the body.
What attaches skin cells to the extracellular matrix by?
Plasmodesmata

Does skin cells have intercellular matrix?
Skin cells have intercellular matrix which controls communication in the skin. This is as a result of the loose outer later of the skin which gives it an identity.
What are anchoring junctions?
They are cells which mechanically attach cells (and their cytoskelentons) to their neighbours or to the extracellular mattrix. They enable group of cells such as epithelium to resist streching forces by connecting the cytoskeletal elements of a cell either to those of another cell or to the extracellular matrix. They are most abundant in tissues that are subjected to sever mechanical stress, such as heart muscle and skin epithelium(epithermis) university of constanta

Where do the cells divide to produce hair?
matrix cells
Why are tendons hard?
Yes, hard but supple. There is a fine line there. When you say hard, I assume you mean tougher than muscle and skin. All tissues are held together primarily by proteins secreted by cells that surround the cells called extracellular matrix. Cells alone are generally not very sturdy. The extracellular matrix is a combination of proteins that vary depending on what part of the body and what cells are secreting the proteins. The main structural proteins are collagens and elastin which are long helical (corkscrew shaped) proteins. Tendons and ligaments have more collagen and elastin than most tissues and this is what accounts for most of their durability. The types of collagen (and other proteins) and how they are hooked together (crosslinked) also has a large effect on the properties of the tissue. For example, the durability of cartilage is also due to extracellular matrix proteins but its character is very different from tendons and ligaments because the types and associations of the proteins is different.
What is a collagens job?
Collagen is a naturally occurring protein.It is found in animalls.It is a fibrous protein found in extracellular matrix and also in connective tissues.Now a days,it is used in cosmetics,to tighten the skin and to prevent wrinkles on the skin
Sto cell line?
Feeder skin fibroblast cells used to provide the extra-cellular matrix for stem cells.
Describe nail formation?
Living skin cells in the finger are what produced fingernails. A fingernail is made of several parts. The nail plate, the nail bed, the cuticle, the nail folds, the lunula, and the matrix are all parts of the fingernail. Nails grow from the matrix and are composed of keratin. When new cells grow, the older cells are pushed out.
