Figure 7. TEM analysis of the Xenopus tropicalis myocardium 8 d after injury. Eight days after injury, some of the injured muscle fibres regenerated via a novel muscle fibre characterized by an irregular muscle fibril arrangement and irregular sarcomere (RM) as well as regenerated sarcolemma (open arrow). An accumulation of mitochondria is seen in the regenerated muscle fibres (A, B), and a karyokinesis‐like nucleus was found in the border cardiomyocytes of regenerated myofibres (C). In addition, CTs with normal morphology are found on the outer surface of regenerated myofibres (A, B). B: Higher‐power view of the dotted line rectangle in A. Scale bar: Size as shown in the figures. Asterisk: Cardiomyocyte; CT: Cardiac telocyte; Mt: Mitochondria; N: Nucleus; RM: Regenerated myofibres; Tp: Telopode; W: Inflammatory cell Image published in: Lv L et al. (2020) © 2020 The Authors.
