Thermo-reversible gelation of self-assembled conducting polymer colloids [PDF]

Nature Communications
Electrically conductive hydrogels based on conducting polymers have found increased use in bioelectronics due to their low moduli that mimic biological tissues, their ability to transport both ionic and electronic charges, and their ease of processing in

Articular chondrocytes from osteoarthritic knee joints of elderly, in vitro expanded in thermo-reversible gelation polymer (TGP), exhibiting higher UEA-1 expression in lectin microarray [PDF]

Regenerative Therapy, 2020
Autologous chondrocytes in vitro expanded, are used as tools of regenerative therapies for cartilage injuries. However, inability to maintain the hyaline phenotype both in vitro and post in vivo transplantation, remains one of the major hurdles for long ...

An Improved Encapsulation Method for Cryopreserving Hepatocytes for Functional Transplantation Using a Thermo-reversible Gelation Polymer. [PDF]

In Vivo, 2020
Thermo-reversible gelation polymer (TGP) can be converted into a gel state upon warming and liquid upon cooling. The present study aimed to demonstrate a new method for cryopreservation and encapsulation of rat hepatocytes using a TGP and their successful transplantation.The isolated rat hepatocytes were microencapsulated using TGP, and stored in ...

A novel human donor cornea preservation cocktail incorporating a thermo-reversible gelation polymer (TGP), enhancing the corneal endothelial cell density maintenance and explant culture of corneal limbal cells. [PDF]

Biotechnol Lett, 2021
Abstract Purpose McCarey-Kaufman’s (MK) medium and Optisol-GS medium are the most commonly employed media for human donor corneal preservation. In this study, we evaluated the preservation efficacy of discarded human donor corneas using a Thermo-reversible gelation polymer (TGP) added to these two media.

Successful engraftment of epithelial cells derived from autologous rabbit buccal mucosal tissue, encapsulated in a polymer scaffold in a rabbit model of a urethral stricture, transplanted using the transurethral approach

Regenerative Therapy, 2021
Background: A pilot study reported an autologous buccal mucosal cell transplant in humans through the trans-urethral route using the buccal epithelium expanded and encapsulated in scaffold—hybrid approach to urethral stricture (BEES-HAUS), a minimally ...

Reversal of senescence-associated beta-galactosidase expression during in vitro three-dimensional tissue-engineering of human chondrocytes in a polymer scaffold

Scientific Reports, 2021
Regenerative medicine applications require cells that are not inflicted with senescence after in vitro culture for an optimal in vivo outcome. Methods to overcome replicative senescence include genomic modifications which have their own disadvantages. We
