Background & Aim: When meniscal tissue is damaged, there is no
gold standard medication and/or surgical treatment that can regenerate
the damaged tissue. Currently, although the most effective
treatment approach is the surgical method-partial meniscectomy, it
provides only symptomatic improvement. The aim of this study is
to develop the stem cell treatment protocol in addition/alternative
to the surgical method adapt it to the clinical practices, suitable for
use in human treatment. For this purpose, all steps of the production
process as a Good Manufacturing Practices (GMP)-grade cellular therapy
product from the collection of the synovial fluid sample from the
patient until the release of the final product; the standard operation
procedure of the production was prepared according to the legal regulations.
Methods, Results & Conclusion: Therefore, firstly mesenchymal
stem cells were isolated from human synovial fluid by xeno-free enzymatic
separation under GMP protocols (ESOGÜ, Clinical Research
Ethics Committee approval, 11/04/2019-20). hSF-MSCs were cultured
until the third passage. Sterility, serology, quality control and stem
cell characterization tests were performed for use in human therapy.
The final product release for use in treatment was prepared in accordance
with the procedure. hSF-MSCs were characterized according to
the minimum standard criteria of the International Society for Cellular
Therapy (ISTC) guidelines. In addition, sterility, serology, endotoxin
and mycoplasma tests were also negative in accordance with
the criteria for release as the final product. Finally, the documentation
of all stages of the cell processing and manufacturing process of this
cellular therapy product has been completed in accordance with the
T.C. Ministry of Health, TITCK “GMP Guideline for Manufactories of
Medicinal Products for Human Use” and “Communiqué on the Licensing
of Human Tissue and Cell Products and the Centres Carrying Out
the Production, Import, Export, Storage and Distribution Activities
of These Products”. As a result, the production process of stem cell
therapy product, which has both regenerative and anti-inflammatory
activity in the treatment of meniscal damage and complies with
legal and ethical regulations, has been made ready for licensing. Acknowledgements:
