Wound healing processes of the integument of the silkworm, especially of the epidermis, were observed histo-cytologically on the larvae injured at the fourth day of the fourth instar. Epidermis at the wound is formed from blood cells gathered there. Mitotic cell multiplication is not observed.
In the epidermis near the wound there are some vacuolated nuclei which may be blood cells entered in the epidermis.
In the moulting period cuticle formation is delayed by several hours, as compared with the normal case. No nodule formation in the new cuticle is often observed at the wound.
Many polynucleated cells are observed in the epidermis near the wound within a scores of hours.
