Table 1. Quantitative analysis of extracellular matrix (ECM) components in the human scapholunate ligament (SLIL) zones and control tissues. For each histochemical and immunohistochemical method, average intensity units (I.U.) ± standard deviation values are shown for each sample. Statistical p values correspond to the comparison of each SLIL zone vs. each control tissue and between both zones of each region using the Mann-Whitney test. Statistically significant values are labeled with asterisks (*). FT: Flexor tendon, CL: Carpal ligament, AC: Articular cartilage, TF: Triangular fibrocartilage, CC: Carpal articular capsule, RT: Retinaculum, D1: dorsal region (part 1), D2: dorsal region (part 2), M1: membranous region (part 1), M2: membranous region (part 2), P1: palmar region (part 1), P2: palmar region (part 2). VHF: Verhoeff histochemistry for elastic fibers, PSR: picrosirius red histochemistry for collagen fibers, COL-I, COL-III and COL-IV: immunohistochemistry for collagens types I, III and IV, respectively, AB: alcian blue histochemistry for proteoglycans, PAS: periodic acid–Schiff histochemistry for glycosaminoglycans, VSC: versican immunohistochemistry.
