Described herein are polymeric drug-carrying nanogels that are capable of targeting to P-selectin for the treatment of cancer and other diseases and conditions associated with P-selectin. Furthermore, in certain embodiments, the nanogels presented here offer a drug release mechanism based on acidic pH in the microenvironment of a tumor, thereby providing improved treatment targeting capability and allowing use of lower drug doses, thereby reducing toxicity.

The invention proposes a polymer solution for visco-supplementation. The polymer solution contains at least one at least partially water-soluble polysaccharide or polysaccharide derivative, one water-soluble alkali salt or alkaline earth salt of polystyrene sulfonic acid, and water, whereby the polymer solution is clear to the eye. Moreover, the invention describes a method for sterilization of the polymer solution. This method is characterized in that a mixture of at least one at least partially water-soluble polysaccharide or polysaccharide derivative, one water-soluble alkali salt or alkaline earth salt of polystyrene sulfonic acid, and water is mixed with at least 0.5 wt. % -propiolactone, and in that the polymer solution is stored at room temperature for at least 24 hours.

Provided herein are materials for the promotion of tissue regeneration, and methods of promoting tissue regeneration and wound healing therewith. In particular, materials displaying laminin-derived peptide sequences that facilitate cell migration into the material, and methods of use thereof, are provided.
