Proven expression of nidogen isoforms. Nidogen-1 has been detected not only in human bone marrow stromal cells (BMSCs)^59,63 but also in human and mouse embryos along with nidogen-2.^27,79,85,135 During the adulthood of human, mouse and rat models, nidogen expression has been broadly found in various tissues, such as muscle,^26,36, 37, 38^,84 vessel,^67,75,136 tendon,¹²⁹ cartilage,78, 79, 80 nerve,^92,94 and fat^54,62,64 (Table 1 for details). The black triangle represents positive expression of nidogen isoforms in the cells or tissues of human (H), mouse (M) and/or rat (R).
