Accessibility Careers. the latter two markers can be useful in the differential diagnosis of leiomyosarcoma and myofibroblastic sarcomas, because the latter are negative for heavy caldesmon and smooth muscle myosin.. positive control slides. Caldesmon is the cytoskeletal-associated protein in the smooth muscle cells, including two subtypes: H-caldesmon and L-caldesmon [5]. Most importantly, these papers accepted without question that myogenic differentiation was present whenever positive expression of H-caldesmon was seen in GIST, whereas we doubted this. To explore this problem, the authors evaluated the expression of traditional muscle markers and high-molecular-weight caldesmon (h-cal), an actin and tropomyosin binding protein that has recently been described as a useful muscle marker, in uterine leiomyosarcoma (LMS), cellular leiomyomata (CL), and endometrial stromal sarcoma (ESS). Weighted Gene Co-expression Network Analysis Identifies CALD1 as a Biomarker Related to M2 Macrophages Infiltration in Stage III and IV Mismatch Repair-Proficient Colorectal Carcinoma. In our study, we found that the positive expression of H-caldesmon in one case was localized in the membrane tumor cells rather than in the cytoplasm where cytoskeletal proteins usually exist. Anti-h-caldesmon seems to be a reliable marker of smooth muscle differentiation, and may assist in the diagnosis of smooth muscle tumors.
