Self-regeneration, in vivo tissue prefabrication,
Brief summary
The purpose of this study is to observe the feasibility and its application of autologous prefabrication for body surface tissues/oranges
Detailed description
In the field of tissue regeneration techniques, the in vitro processes and other exogenous factors still have many uncertainties. These uncertainties have hampered road to the clinical application. As the importance of in vivo environment has aroused more awareness, the investigators validated the hypothesis that the feasibility of self-regeneration prefabricated unaided by any in vitro culture process or exogenous elements.
Interventions
tissue/ organ is prefabricated in vivo independent of exogenous factors for replacement/ reconstruction purposes

Eligibility
Inclusion criteria
* With body surface tissue or organ defects (e.g., ear, nose, bone and joint) requiring reconstruction.
Exclusion criteria
* evidence of infection, ischemia, ulcer or other pathological changes within the prefabricated area which defined as not suitable for tissues regeneration * history of delayed healing, radiational therapy; * significant renal, cardiovascular, hepatic and psychiatric diseases; * significant medical diseases or infection (including but not limited to the carrier of hepatitis B virus or HIV); * BMI \>30; * history of any hematological disease, including leukopenia, thrombocytopenia, or thrombocytosis; * Evidence of malignant diseases * unwillingness to participate.
Design outcomes
Primary
| Measure | Time frame | Description |
