“…Peritubular myoid cells, as well as other contractile cells, express markers for alpha‐actin MFs (Maekawa et al, 1991) and for desmin IF (Ježek et al, 1996). This peritubular tissue in the testes of the lizards analysed here presents a marked immunohistochemical reaction for α‐SMA, in the same way as observed in quails, roosters, turkeys and ducks (Aire & Ozegbe, 2007; Maretta & Marettová, 2004; Rothwell & Tingari, 1973; Van Nassauw et al, 1993) and sheep, monkeys, rabbits and Korean water deer and Reeves' muntjac (Abd‐Elmaksoud, 2009; Schlatt et al, 1993; Sohn et al, 2013; Steger & Wrobel, 1994). The activity of these filaments is responsible for the contraction of seminiferous tubules, which results in fluid movement and propulsion of sperm (Rossi et al, 2002).…”
