We want to examine the effects of one of the metal on Rat testis and we need to compare the number of spermatids, spermatocytes, spermatogonia, Sertoli and Leydig cells and connective tissue, how to score the (levels) damaged tissue?
The integrity and structural modifications occuring in intratubular sections could be evaluated as originally described in details in our laboratory by Milazzo et al. (2008) : https://academic.oup.com/humrep/article/23/1/17/563606
Then, this Score was a little modified (Dumont et al., 2015) : Article Assessment of the optimal vitrification protocol for pre-pub...
Briefly, a score between 0 and 5 was given for (i) nuclear and (ii) epithelial alterations, with 0 representing the complete absence of alteration and 5 representing the most severe alterations. Therefore, the global score for each seminiferous section varied between 0 and 10 for the fresh controls and frozen‐thawed testicular samples.
The structure of a seminiferous tubule in sections was judged to be intact when epithelial and nuclei scores were both without any morphological alteration.
For each testis, the global score of peripheral, central and global areas could be determined independently by taking the mean of the scores of 30 seminiferous tubules. "Morphological alterations" correspond to the global scores normalized to 100 (originally measured on a scale of 10).
Hoping that this complement reply will be useful,
Dear community of RG, feel free to add modifications & precisions to my Answer!
I work on quantitation of spermatogenic cell yeild and leydig cell indecies, correction of Sertoli cells and abrocrobies formus , quantity of voleum dencities of of seminiferous tubules an other paramerters determine what type of these I can help you with my pleasure
Hey Mahesh, You can quantify various cell types by performing a blinded scoring analysis, by point counting method for instance. You can stain the testicular sections with germ cell, leydig cell and Sertoli cell specific markers. In addition, you can perform morphometric analysis of the testicular sections, score the sections based on the morphological variations (for example, epithelial arrangement of the tubules, tubular appearance, immune cell infiltration within the tubules, presence of the most advanced germ cell types).
Well I would mention some recent ones from my group, which may give you some idea for different analytical approaches which could possibly be employed: https://www.frontiersin.org/articles/10.3389/fendo.2018.00467/full
