Figure 6
Anti-collagen-I/III immunostaining of native and acellular human scalp. Both collagen type I (green colour) and III (red colour) are present throughout the epidermis and dermis in the native samples. After acellularization, the cells cannot be depicted between the dermal papillae anymore (white asterisk) with the anti-collagen staining of acellular samples being overall more intense compared to the native samples. d, dermis; e, epidermis; white dotted line, dermal papilla; white dotted squares labeled with number 1, uniformly distributed collagen types I/III in stratum papillare of the dermis; white dotted squares labeled with number 2, dense collagen types I/III in stratum reticulare of the dermis. Scale bars: 50 μm.
