The present invention provides a new structure made of collagen for
improving promotion of nerve tissue regeneration, curing and regeneration
of a defective part of a soft biological tissue and so on without using
laminin or nerve growth factor (NGF), and a member for tissue
regeneration including the same. The structure made of collagen according
to the present invention has a thin film multilocular formation and
therefore a new structure different from a colloid form, a gel form, and
a fiber form. Therefore, when the new structure made of collagen
according to the present invention is used as a member for tissue
regeneration, surprisingly, promotion of regeneration, shortening of a
treatment period, functional recovery, or the like of bodily tissue such
as nerve tissue, subdermal tissue, submucosal tissue, membranous tissue,
fat tissue, muscle tissue, skin tissue, and gingival tissue can be
improved. Furthermore, when the structure according to the present
invention is used to a patient having neuropathic pain, the member has an
effect on the disappearance of the pain.
