22/8/2019  Skin aging is accompanied by various invisible physiological dysfunctions and visible morphological changes [6,7]. As the skin ages, the elasticity decreases, making it appear to be sagging and wrinkled, and additionally, the skin becomes dry. In aging skin, the number of melanocytes decreases gradually, but the

The minor axis of isolated melanosomes significantly increased, and as a consequence, the aspect ratio (major/minor axes) significantly decreased with age. These morphological parameters

age. Indeed, a loss of melanosomes (melanin-containing granules produced by melanocytes) and variation in their colour with age in non-integumentary mammalian tissues have been reported due to a decrease in the photo-ionization thresholds caused by lipofuscin adhered to their surface and in the metal-binding capacity (Hong & Simon 2005; Liu et al.

However, when noise was applied to the pigmented strain, pigmented VAD mice showed poorer recovery of auditory thresholds after noise exposure than pigmented control mice. In conclusion, hearing thresholds of VAD mice were impaired by

Aging affects the biological function of the fibroblasts, both in vivo and in vitro, and this phase may be related to the responses to the IGFs. Although IGF-1R levels are similar during this life phase, only the young, rather than the senescent, human fibro-blasts proliferate in response to the stimulus of IGF-1

ber of changes in both epidermis and dermis, commonly referred to as skin aging. These features include changes in the epidermis, such as the presence of light brown spots ( age spots ), and in the dermis, such as a reduction in the volume and quality of the dermis that accompanies wrinkle formation.
