The present invention provides a method for the repair of subcutaneous or dermal tissue in a subject, comprising in one aspect the injection of a suspension of allogeneic dermal fibroblasts into the subject. By injecting a suspension of allogeneic cells, the invention provides, for example, long-term augmentation of the subadjacent tissue without the disadvantages that accompany the preparation and/or use of presently available materials such as autologous fibroblasts cells or collagen. According to a first aspect of the invention there is provided a method for the augmentation of subcutaneous or dermal tissue in a subject, which method comprises the steps of: (i) providing a suspension of allogeneic dermal fibroblasts; and (ii) injecting an effective volume of the suspension into tissue subadjacent to the subcutaneous or dermal tissue so that the tissue is augmented. The method is preferably cosmetic.
A method for the augmentation of subcutaneous or dermal tissue in a subject, which method comprises the steps of:
The method of any preceding claim, in which the fibroblasts are passaged.
The method of any preceding claim, wherein the defect is a rhytid, stretch mark, a depressed scar, a cutaneous depression of non-traumatic origin or an under-development of the lip.
The method of any preceding claim, wherein the suspension further comprises fibrin in an amount effective to form an injectable.
The method of any preceding claim, wherein the suspension further comprises collagen and/or hyaluronic acid.
The method of any preceding claim, which further comprises the steps of:
The method of any preceding claim, in which the subject is human.
The method of any preceding claim wherein between 104 and 108, for example between 106 and 108, preferably about 1-5×107, for example 1×107 4×107, fibroblasts are injected.
The method of any preceding claim wherein a volume of about 1 ml of suspension is injected.
A method according to any preceding claim wherein
Use of allogeneic dermal fibroblasts, optionally including a preservation medium which is HypoThermosol®, preferably HypoThermosol® FRS (Registered Trade Mark BioLife Solutions, Inc.), in the treatment of subcutaneous or dermal tissue defects.
Use of allogeneic dermal fibroblasts, optionally including a preservation medium which is HypoThermosol®, preferably HypoThermosol® FRS (Registered Trade Mark BioLife Solutions, Inc.), in the manufacture of a medicament for the cosmetic treatment of subcutaneous or dermal tissue defects.
A composition for the augmentation of subcutaneous or dermal tissue in a subject, which comprises a suspension of allogeneic dermal fibroblasts in a preservation medium which is HypoThermosol®, preferably HypoThermosol® FRS (Registered Trade Mark BioLife Solutions, Inc.)
