As far as I know they are in the epidermis, so no.
Adipose tissue is primarily found in the subcutaneous layer of the skin, which is also known as the hypodermis. This layer lies beneath the dermis and serves as insulation, energy storage, and cushioning for underlying tissues and organs. Adipose tissue can also be found in small amounts within the dermis and surrounding certain organs throughout the body.
Osseous types of connective tissue forms the bony skeleton. Adipose is the types of connective tissues composes dermis of skin.
Adipose tissue
Adipose tissue is also called fat tissue. It is found under the skin, around organs such as the eyes and kidneys, on the surface of the heart, around certain joints, and in some abdominal members as an "apron" over the abdominal organs. Your skin has three layers. Epidermis, dermis, and hypodermis. Adipose tissue is in the hypodermis.
The tissue that makes up most of your skin is Epithelial tissue.
The dermis contains dense irregular connective tissue with elastic fibers and collagen type I. It also contains very few fibroblast cells.
The two basic tissues that make up skin are the epidermis and the dermis. The epidermis is the outermost layer of skin, providing a protective barrier, while the dermis lies beneath the epidermis and contains blood vessels, nerves, and glands.
the hypodermis
The dermis is a layer of skin between the epidermis and subcutaneous tissues, and is composed of two layers, the papillary and reticular dermis.
Adipose tissue is primarily found in the subcutaneous layer of the skin, also known as the hypodermis. This layer lies beneath the dermis and serves as a cushion for underlying structures, providing insulation and energy storage. The presence of adipose tissue in the hypodermis helps regulate body temperature and protect against trauma.
The hypodermis (subcutaneous layer, or superficial fascia) lies between the dermis and underlying tissues and organs. It consists of mostly adipose tissue and is the storage site of most body fat. It serves to fasten the skin to the underlying surface, provides thermal insulation, and absorbs shocks from impacts to the skin.
Heparin is not typically found in the dermis; instead, it is primarily associated with mast cells and basophils in the connective tissues throughout the body. While heparin is present in various tissues, its primary role is as an anticoagulant within the bloodstream. The dermis contains other components such as collagen, elastin, and glycosaminoglycans, which contribute to skin structure and function.
