Human TM cells derived from donors 19, 34, and 49 years of age were plated at 5000 cells per well on 8-well chamber slides in Dulbeccos modified Eagles medium containing 10% fetal bovine serum (FBS) (Sigma-Aldrich). The medium was changed to 0.1% FBS for 2 hours before treatment. Biotinylated albumin (b-albumin; molar ratio of biotin to albumin was 8:1; Sigma-Aldrich), b-sCD44, or -p b-sCD44 (0.1 ng) was added to the wells and the slides were incubated at 4°C for 1 or 2 hours. Excess b-albumin, b-sCD44, or -p b-sCD44 not bound to the cell surface was removed by aspiration and fresh media was added. Cells were also treated with 1 μg of HA or with 1 ng of the 10-mer HA binding peptide, KNGRYSISRT, corresponding to the first HA binding site of sCD44 (amino acid residues 38 through 47). The 10-mer HA binding peptide was synthesized by Genemed Synthesis, Inc. (San Francisco, CA), and acetylated on N-terminus and amidated on C-terminus to prevent protease degradation. Control peptides were a ...

Purpose. human TM cells morphologically and started to specific many guns of TM cells while ceasing to specific pluripotency guns such as Nanog, April4, and Sox2. Functionally, the ability was created by these cells to phagocytose particles. Finally, publicity to dexamethasone or phorbol 12-myristate acetate triggered a specific boost in the creation and release of myocilin and matrix metalloproteinase-3, respectively, behavior quality of TM cells. Results. Our data show that iPSCs can be induced to assume a phenotype that resembles native TM cells in many important aspects. Not only do these cells represent a valuable research tool, but transplantation into glaucomatous eyes with elevated IOP may also restore function to the TM, resulting in re-establishment of IOP. … In order to induce iPSCs to differentiate into TM-like cells, iPSCs were cocultured with the human cell line hTM530 for up to 21 days. This immortalized cell line was used here since it grows at a very consistent rate and ...

The major structural change in the human trabecular meshwork (TM) of eyes with primary open-angle glaucoma (POAG) is an increase in extracellular matrix (ECM) in the juxtacanalicular region of the TM. There is evidence that treatment with TGF-beta2 causes an induction of ECM deposition in cultured human TM cells and that TGF-beta2 is causatively involved in the JCT ECM increase in POAG. In the present study, we investigated the effects of connective tissue growth factor (CTGF) on the biology of cultured human TM cells. CTGF is a downstream mediator of TGF-beta2-signaling, which is expressed at high amounts in the human TM in situ. HEK293 cells were transfected with an eukaryotic expression plasmid containing the coding sequences of human CTGF. Secreted CTGF was isolated and purified by chromatography. Primary human TM cells were incubated for 24 h with CTGF at concentrations of 2.5-100 ng/ml. Following treatment with CTGF, the expression of various ECM components that are expressed in the JCT, ...

Scientists have long known that a small protein Dr. Saikumar was studying, Transforming Growth Factor-Beta (TGF-B), behaves in a paradoxical way. When a cell begins undergoing the transformation into a cancerous state, TGF-B can stop that growth and protects us from developing cancer. But if that cell escapes the TGF-B surveillance, then it will advance into a full-blown cancer cell and TGF-B can help it thrive and spread faster.. Turning off this treasonous action of TGF-B alone may indeed be advantageous, the pathologist said.. Although TGF-B has received intense scrutiny in the 30 years since its discovery, little is understood as to just how it turns from a tumor suppressor into a tumor promoter. Researchers found that if they suppress TGF-B activity to starve a cancerous tumor, a new tumor is likely to start growing, since the proteins helpful function in preventing new cancerous development is also switched off.. But Dr. Saikumar found a clue in an obscure protein called TMEPAI, and ...

Abstract: : Purpose: The focus of the present study was to examine in a controlled fashion the cellular localization of native and recombinant myocilin (MYOC) in human trabecular meshwork (HTM) cells. Methods: HTM and COS-7 cells were either mock transfected or transfected with cDNAs encoding green fluorescent protein (GFP), MYOC/GFP, signal peptide (SP)/GFP, or SP/GFP/KDEL. Forty-eight hours post-transfection supernatants were collected, centrifuged at 2000g, concentrated ten-fold then centrifuged again at 14,000g. Pellets, whole cells and supernatants were solubilized separately in buffer containing 2% SDS and analyzed by SDS-PAGE. Fractionated proteins were transferred to nitrocellulose and analyzed by western blot using affinity purified anti-MYOC, anti-GFP and anti-beta-actin antibodies. Results: Native MYOC, recombinant MYOC and protein products of all control constructs were present in varied amounts in all four preparations tested (pellet 1, pellet 2, whole cell lysate and supernatant). ...

Inside all three new Dermaheal products - highest concentrations in Ultra Renewal Cream. Youll want to remember the name TGF-B3. It is probably the most potent human growth factor in existence. And its incredibly rare/scarce because your body only expresses it once in your lifetime - when youre a baby in the womb.. If youve ever marvelled at how a human foetus grows from just a set of basic cells into a near fully-formed baby in just a few months, youll appreciate that how advanced the growth factors are that go to work while a babys in gestation. TGF-B3 is one of these. And its so powerful that it gives baby the ability to heal without any scarring.. Ever notice how quickly and blemish-free a young childs skin heals? Thats because of the residual TGF-B3 thats still present after birth. It disappears completely after a while, your super skin healing abilities are lost forever. Until now. With new Dermaheal, you can recapture that kind of skin-healing power as an adult.. ...

Transforming Growth Factor beta3: A TGF-beta subtype that plays role in regulating epithelial-mesenchymal interaction during embryonic development. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta3 and TGF-beta3 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.
