Recent work in preservation of female fertility as well as new information on the nature of spermatogonial stem cells has prompted an investigation into the possibility of an effective clinical-grade procedure for the cryopreservation of testicular cells and/or tissue.
The feasibility of Treg based therapy is widely accepted, provided that tailor-made clinical grade procedures for isolation and ex vivo cell handling are available.
Presenters stressed that this will require the development of routine clinical-grade procedures for the interpretation of data and return of results.
The empirical testing methods and Superpave grading procedure that were developed mainly for unmodified bitumens have failed in many cases to predict the performance of modified bitumens.
Maybe it is a new additional key feature to the conventional grading procedure to separate tumors that are difficult to distinguish, for example, grade II tumors from grade III ones or grade III tumors from grade IV ones.
Possible enhancements to the grading procedure may include integrated grading of color photos and fluorescein angiograms for the evaluation of the activity and progression of chorioretinal lesions.
This grading procedure has been used in numerous clinical trials and has shown good to excellent reproducibility for assessment of vascular lesions and macular edema.
In the present study, the feasibility of a clinical-grade cryopreservation procedure for human testicular cells and tissue obtained from sexual reassignment patients was studied.
Reliability depends largely on grading procedures and question format.
We hypothesized that molecular characterization of the grade may allow for full exploitation of the association between the grade and relapse beyond the ability of traditional grading procedures.
