Inventors: COTSARELIS, George; United States of America 193212 ITO, Mayumi; United States of America 19107

Assignee: HE TRUSTEES OF THE UNIVERSITY OF PENNSYLVANIA United States of America 19104-6283

Abstract:
The present invention provides methods of treating baldness in a subject and generating new hair follicles, comprising epidermal disruption and administration of a compound that promotes a differentiation of an uncoramitted epidermal cell into a hair follicle cell. The present invention also provides methods for hair removal and inducing hair pigmentation.

First Claim:
A method for generating a hair follicle in a scalp, eyebrow, or scarred region of a subject, the method comprising the steps of: (a) disrupting an epidermis of said scalp, eyebrow, or scarred region; and (b) contacting said scalp, eyebrow, or scarred region with a compound or factor that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell, thereby generating a hair follicle in a scalp, eyebrow, or scarred region of a subject 2. A method for treating an androgenetic alopecia (AGA) hi a scalp, the method comprising the steps of: (a) disrupting an epidermis of said scalp; and (b) contacting said scalp with a compound or factor that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell, thereby treating AGA in a scalp.

Description:
The present invention provides methods of treating baldness in a subject and generating new hair follicles, comprising epidermal disruption and administration of a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell. The present invention also provides methods for hair removal and inducing hair pigmentation.

Background:
Follicular neogenesis is defined as the generation of new hair follicles (HP) after birth. Humans are born with a full complement of HF, which can change in size and growth characteristics as in early baldness or can ultimately degenerate and disappear as in late stages of baldness or in permanent scarring (cicatricial) alopecias. Therefore, the generation onew HF is desirable in the treatment of common baldness as well as less common hair loss conditions, such as discoid lupus erytbematosis, congenital hypotriebosis, lichen planopilaris and other scarring alopecias.

Summary:
The present invention provides methods of treating baldness in a subject and generating new hair follicles (HF), comprising epidemial disruption and administration of a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell. The present invention also provides methods for hair removal and inducing hair pigmentation.

In one embodiment, the present invention provides a method for generating a hair follicle in a scalp, eyebrow, or scarred region of a subject, comprising the steps of: (a) disrupting the epidermis of the scalp, eyebrow, or scarred region; and (b) contacting the scalp, eyebrow, or scarred region with a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell, thereby generating a hair follicle in a scalp, eyebrow, or scarred region of a subject.

In another embodiment, the present invention provides a method for generating a hair follicle in a scalp, eyebrow, or scarred region of a subject, comprising the steps of: (a) disrupting the epidermis of the scalp, eyebrow, or scarred region; and (b) contacting the scalp, eyebrow, or scarred region with a factor that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell, thereby generating a hair follicle in a scalp, eyebrow, or scarred region of a subject.

In another embodiment, the present invention provides a method for treating baldness in a scalp, eyebrow, or scarred region, comprising the steps of: (a) disrupting the epidermis of the scalp, eyebrow, or scarred region; and (b) contacting the scalp, eyebrow, or scarred region with a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle (HF) cell, thereby treating baldness in a scalp, eyebrow, or scarred region.

In another embodiment, the present invention provides a method for treating baldness in a scalp, eyebrow, or scarred region, comprising the steps of: (a) disrupting the epidermis of the scalp, eyebrow, or scarred region; and (b) contacting the scalp, eyebrow, or scarred region with a factor that promotes a differentiation of an uncommitted epidermal cell into a HF cell, thereby treating baldness in a scalp, eyebrow, or scarred region. In another embodiment, the baldness is an androgenetic alopecia (AGA)-induced baldness. Each possibility represents a separate embodiment of the present invention.

In another embodiment, the present invention provides a method for removal of an HF from a skin or scalp of a subject, comprising the steps of: (a) disrupting an epidermis of the skin or scalp; and (b) contacting the skin or scalp with either: (i) an 130F protein; (ii) an EGF receptor; (iii) a nucleotide encoding an EGF protein or EGF receptor; or (iv) a compound or factor that activates a EGF protein or EGF receptor, thereby removing an HF from a skin or scalp of a subject.

In another embodiment, the present invention provides a method for increasing a size of a hair follicle in a scalp, eyebrow, or scarred region of a subject, the method comprising the steps of: (a) disrupting an epidermis of the scalp, eyebrow, or scarred region; and (b) contacting the scalp, eyebrow, or scarred region with a compound or factor that promotes a differentiation of an P-762smile.gifC uncommitted epidermal cell into a hair follicle cell, thereby increasing a size of a hair follicle in a scalp, eyebrow, or scarred region of a subject.

In another embodiment, the present invention provides a method for generating a hair follicle in a scalp, eyebrow, or scarred region of a subject, comprising the steps of (a) disrupting an epidermis of said scalp, eyebrow, or scarred region; and (b) contacting said scalp, eyebrow, or scarred region with a cell selected from (a) a precursor cell that is capable of differentiation into a hair follicle cell; (b) an inductive cell that is capable of inducing differentiation of an uncommitted epidermal cell into a hair follicle cell; or (c) a hair follicle or portion thereof, thereby generating a hair follicle in a scalp, eyebrow, or scarred region of a subject. In another embodiment, step (b) is performed 3-12 days after step (a). Each possibility represents a separate embodiment of the present invention.

In another embodiment, the present invention provides a method for treating an AGA in a scalp, comprising the steps of: (a) disrupting an epidermis of said scalp; and (b) contacting said scalp with a cell selected from (a) a precursor cell that is capable of differentiation into a hair follicle cell; (b) an inductive cell that is capable of inducing differentiation of an uncommitted epidermal cell into a hair follicle cell; or (c) a hair follicle or portion thereof, thereby treating an AGA in a scalp. In another embodiment, step (b) is performed 342 days after step (a). Each possibility represents a separate embodiment of the present invention.
