Biomaterials are designed to improve impaired healing of injured tissue. To accomplish better cell integration, we suggest to coat biomaterial surfaces with bio-functional proteins. Here, a mussel-derived surface-binding peptide is used and coupled to CXCL12 (stromal cell-derived factor 1α), a chemokine that activates CXCR4 and consequently recruits tissue-specific stem and progenitor cells.

Interactions of hyaluronan (HA) and tumor and stromal cells are highly discussed as one of the major contributors in tumor progression and metastasis. The balance of HA in the tissue is highly regulated by two key enzyme classes; hyaluronan synthases (HAS) and hyaluronidases (HYAL). Current reports hint that the HA amount in the tissue is correlated with poor prognosis in melanoma, the most life-threatening skin tumor.

Functional biomaterials that are able to bind, stabilize and release bioactive proteins in a defined manner are required for the controlled delivery of such to the desired place of action, stimulating wound healing in health-compromised patients. Glycosaminoglycans (GAG) represent a very promising group of components since they may be functionally engineered and are well tolerated by the recipient tissues due to their relative immunological inertness. Ligands of the Epidermal Growth Factor (EGF) receptor (EGFR) activate keratinocytes and dermal fibroblasts and, thus, contribute to skin wound healing.
