About this study
Official title: Study of Tissue Engineering for Hair Follicle Regeneration
This study is to try to maintain cultured dermal papilla cells in spherical structure in vitro before transplanting into dermis in vivo. Also, this study is aimed in clarifying actual mechanism of inducing hair follicle by dermal papilla cells.
Read the detailed description
Hair transplantation is an well-documented way of treating hair loss. Hair transplantation is based on redistribution of hair follicles without any new follicle formation. It has been long that a lot of researchers have focused on developing skills in regenerating hair follicles. However, cultured dermal papilla cells lose the ability of inducing hair follicle formation after several generations in vitro culture. Our study is aiming in culturing dermal papilla cells in vitro and maintain their spherical structure before transplanting into dermis in vivo. Meantime, this study may help clarify the actual mechanism of inducing hair follicle by dermal papilla cells.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 25 Jul 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
