Superficial epidermal cells of the teleost Pimelodus maculatus show modifications after heat exposure (36 degrees C) for 3 days. Heat treatment affects the arrangement of cytoplasmic filaments resulting in the disappearance of the microridges. The fish maintained at 36 degrees C during 3 days show modifications in the cytoplasmic organization of their superficial epidermal cells. The most conspicuous alterations are: apparition of lysosomes (including autolysosomes), hypertrophy of the GOLGI complexes, disappearance of the RER, and modifications in the nuclear envelope. Epidermal cells maintained at 36 degrees C for 10 days are transformed into horny-like cells. The differences and resemblances with keratinized cells of terrestrial vertebrates are described and discussed.
鲶鱼（Pimelodus maculatus）的表皮浅层细胞在36摄氏度热暴露3天后会出现变化。热处理会影响细胞质细丝的排列，导致微嵴消失。在36摄氏度下维持3天的鱼，其表皮浅层细胞的细胞质组织会发生变化。最明显的改变是：溶酶体（包括自溶酶体）出现、高尔基体复合体肥大、粗面内质网消失以及核膜改变。在36摄氏度下维持10天的表皮细胞会转变为角质样细胞。文中描述并讨论了与陆生脊椎动物角质化细胞的异同。
