If a diabetic patient experiences prolonged elevated blood glucose after a surgical wound, which consequence follows regarding collagen synthesis?

A)Increased fibroblastic proliferation occurs locally
B)Collagen cross-linking becomes severely impaired
C)Matrix metalloproteinase activity decreases greatly
D)Growth factor signaling is strongly upregulated

💡 Explanation

Hyperglycemia impairs the non-enzymatic glycation of collagen, a process that interferes with normal collagen cross-linking; this impairs wound healing because collagen cross-linking is vital for tensile strength. Therefore, collagen cross-linking is impaired, rather than increased fibroblastic proliferation, which would promote collagen deposition under normal conditions.
