The Effect seen in most Superficial Epidermal Layers
A hypothetical drug causes blood vessels to grow from the dermis into the superficial stratum granulosum of the epidermis it will thicken the epidermal layers. Epidermis is the outermost of the three layers that make up the skin so a hypothetical drug will thicken such an outermost layer.
The melanocytes are accountable for skin color that is observed in the basal cells. The epidermis has no blood stocks and depends on the spread from the dermal cells for its metabolic demands. The dead-cell zone of the stratum corneum presents the stability from H2O failure that allows vertebrates to remain on the area.
The thickness of the superficial epithelial layer would increase while there will be no effect on the deeper layers and they will remain the same.
Further Explanation:
The skin of our body is technically known as the cutaneous membrane. The major role of the skin is to protect the organs and tissues of the body from any damage from abrasions, detergents, and microorganisms. For example, many bacteria are present on skin but they are not able to enter in the presence of healthy and intact skin. The skin is composed of three layers which are epidermis, dermis, and subcutaneous tissue.
The outermost thin layer is called the epidermis. This layer protects the body from microbial infection and senses the touch. It is further segregated into five layers. The most superficial or the outer layer is stratum corneum followed by stratum lucidum, stratum granulosum, stratum spinosum, and the deepest layer stratum basale.
The epidermal layer is followed by the dermis. It consists of blood vessels that provide nourishment to the overlying epidermis and also to itself. The blood vessels also help in the transport of oxygen and waste materials. The dermis also has nerves for signal transduction. The subcutaneous also contains nerves and blood vessels. It also contains a fat layer to protect the internal organs from physical trauma.
The growth of blood vessels into the stratum granulosum from the dermis would result in the thickening of the respective layer. This is because the stratum granulosum does not originally contain the blood vessels. The formation of blood vessels and subsequent passage of blood into this layer would increase the thickness of the layer. While the deeper layers would remain unaffected as no new growth of blood vessels has taken place there.
