Anti-DDR1/CD167a Antibody is a neutralizing monoclonal antibody targeting the receptor tyrosine kinase DDR1, acting by blocking its interaction with extracellular matrix collagen. The compound is an essential tool for investigating how cell-matrix interactions regulate stem cell fate and tissue morphogenesis, aiming to reveal the molecular logic of multi-lineage differentiation and organ regeneration by intervening in the DDR1 signaling axis.
