Abstract: Myoid cells in the calf's thymus were observed at histological and ultrastructural levels. The cells appeared in the thymic medulla, but not in the cortex, and comprised 2.4% of all cells in the medulla. The cells were round to oval cells, 15〜20μ in size, with an oval nucleus. The cytoplasm of the cells was filled with myofibrils which ran extremely variable courses. In the myofibrils, Z-and M-lines, and A-and I-bands were clearly distinguished. In cross-sections of the A-band, both thick and thin filaments were observed to be arranged in hexagonal pattern. T-system like structures were sometimes present, but showed no regular arrangements. A few of the myoid cells contained a basement membrane, and desmosomes with neighbouring epithelial reticular cells.
