The present invention relates to a new method for repairing human or
animal tissues such as cartilage, meniscus, ligament, tendon, bone, skin,
cornea, periodontal tissues, abscesses, resected tumors, and ulcers. The
method comprises the step of introducing into the tissue a
temperature-dependent polymer gel composition such that the composition
adhere to the tissue and promote support for cell proliferation for
repairing the tissue. Other than a polymer, the composition preferably
comprises a blood component such as whole blood, processed blood, venous
blood, arterial blood, blood from bone, blood from bone-marrow, bone
marrow, umbilical cord blood, placenta blood, erythrocytes, leukocytes,
monocytes, platelets, fibrinogen, thrombin and platelet rich plasma. The
present invention also relates to a new composition to be used with the
method of the present invention.
