Stimulation of hair growth
First Claim
1. A method of inducing hair follicle development and hair growth of a desired hair type in part of the skin of a mammal said skin having an outer epidermis layer and an inner dermis layer, which method comprises the steps of:
- selecting at least one lower follicular dermal cell to provide selected dermal cell, culturing the selected dermal cell so as to produce cultured dermal cells;
forming an opening in the outer epidermis layer of said part of the mammal; and
introducing cultured dermal cells through said opening in the epidermis layer into contact with the dermis layer in proximity to the epidermis and with at least some of said cultured dermal cells in contact with epidermal cells.

Abstract
The present invention relates to a method of stimulating hair growth in part of the skin of a mammal. The method comprises selecting lower follicular dermal cells and culturing them. An opening is then formed in the skin and the cultured dermal cells introduced through the opening in the outer epidermis layer of the skin into contact with the dermis, with said cultured dermal cells in association with epidermis cells.
The invention also provides a hair growth stimulating combination comprising cultured lower follicular dermal cells in admixture with epidermis cells, as well as such cultured dermal cells for use in the preparation of an injection composition for stimulating hair growth in human skin.

12. A method of treatment of the scalp skin area of a human subject, which area has sufficient hair loss and which has an outer epidermis layer and an inner dermis layer, which method comprises the steps of:
-
(a) selecting at least one human scalp lower follicular dermal cell; (b) culturing at least one human scalp dermal cell so as to produce cultured dermal cells; (c) forming an opening in the outer epidermis layer of said human scalp skin area; and (d) introducing said cultured dermal cells through said opening in the epidermis layer into contact with the dermis layer in proximity to the epidermis and with at least some of said cultured dermal cells in contact with epidermal cells. - View Dependent Claims (13, 14)
