These are composed of specialized cells that are called
chondrocytes which function in the maintenance of the integrity of the cartilage.
The choice of the somatic cell for reprogramming, the reprogramming technology chosen, and the differentiation techniques utilised, all work synergistically towards the production of mature iPSCs - derived
chondrocytes which are comparable to patient - derived chondrocytes, in line with Good Manufacturing Practice guidelines for an «off - the - shelf» stem cell product.

Then, to boost the number of cells,
which is another hurdle in tissue engineering, the researchers mixed the
chondrocytes with human mesenchymal stem cells from bone marrow.
To create a new bioink, Gatenholm's team mixed polysaccharides from brown algae and tiny cellulose fibrils from wood or made by bacteria, as well as human
chondrocytes,
which are cells that build up cartilage.
The Rho - kinase inhibition stimuli under low oxygen conditions (of 5 percent oxygen atmosphere),
which is a condition corresponding to conditions in the body's cartilage, produced a more effective increase in
chondrocyte - specific gene expression and synthesis of extracellular matrix components by HCS - 2 / 8 cells.
Researchers at the Feinstein Institute know how to make cartilage from a mixture of cells called
chondrocytes, nutrients to feed them, and collagen,
which holds it all together.
Furthermore, organ cultured cartilage from ACH mice treated with statin resulted in increased expression of the aforementioned three genes and also in Runx2 and Col10a1,
which indicated that statin stimulated both the differentiation and maturation of ACH mouse
chondrocytes.
Rho - kinase inhibitor Y - 27632 (ROCKi) is a potential drug molecule,
which has been reported to support the gene expressions typical for the
chondrocytes, thus restricting their phenotypic conversion to fibroblastic cells upon the cellular expansion.
The cellular stretching relates to stresses,
which are directed to
chondrocytes during the mechanical load.
In addition to iPS cells derived from progeria - patients, the researchers successfully applied their method to adult mesenchymal stem cells,
which can differentiate into a variety of cell types, including adipocytes, osteoblasts,
chondrocytes, cardiomyocytes, and, as described lately, beta - pancreatic islets cells.
However, autologous
chondrocytes lack long term proliferation and functionality in vitro, and so another cell source is being searched for
which could produce
chondrocytes with an increase in functional lifetime.
Utilising both
chondrocytes as a starting material and non-integrating mRNA technology as a reprogramming strategy, the group aimed to remove the risk of epigenetic memory of somatic cell of origin,
which can affect future differentiation propensity, and reduces the risk of abnormalities being introduced during reprogramming.
Vitamin C also works as an antioxidant to limit free - radical damage to tissues, and boosts the growth of fibroblast and
chondrocyte cells,
which produce connective tissue fibers and cartilage (6).
