The present invention provides ocular cells, genetically modified by a CRISPR system targeting the expression of B2M for ocular cell therapy. The invention further provides methods of generating an expanded population of genetically modified ocular cells, for example limbal stem cells (LSCs) or corneal endothelial cells (CECs), wherein the cells are expanded involving the use of a LATS inhibitor and the expression of B2M in the cells has been reduced or eliminated. The present invention also provides a cell populations, preparations, uses and methods of therapy comprising said cells.

日期:——
Herein visiblelight is used to induce RAFT polymerization from protein for preparing protein-polymer conjugates at ambient temperature. Polymerization is fast and can be conveniently controlled with irradiation time. By site-specific polymerization of NIPAm to protein, the protein activity is maintained and in certain cases it presents an efficient on-off-switchable property.

Provided are methods for linking polypeptides (including peptides and proteins) to other moieties using radical imitated thiol-ene chemistries, for example, modifying a polypeptide by introducing reactive thiol groups and reacting the thiol groups with olefin-containing reagents or alkyne-containing reagents under conditions that support radical thiol-ene or thiol-yne reactions. The reactive thiol groups have greater activity for radical thiol-ene reactions that a cysteine thiol group, including thiol groups that are separated from the peptide backbone by at least two carbon atoms, for example, the thiol group of a homocysteine residue. Also provided are compositions and biomaterials containing the linked polypeptides, for example, peptide and protein conjugates, and thiol-ene based biocompatible hydrogel polymers, and their uses in the medical field.
