Answer:
The correct answer is - Associated with the Sertoli cells in the seminiferous tubule.
Explanation:
Interstitial cells are found between seminiferous tubules and Each spermatogonial cell undergoes the process of spermatogenesis process and produces sperms in the lumen of seminiferous tubules.
This could be possible only due to GFP gene expresses only in spermatogonia, we can expect to find GFP + cells associated with the Sertoli cells in the seminiferous tubules.
Therefore, Spermatogonia are associated with Sertoli cells in the seminiferous tubules of the testis.
