| 1. | They are left with round spermatids, the precursors of sperm.
|
| 2. | The spermatogenous cells give rise to spermatids via mitotic cell division.
|
| 3. | They injected these spermatids into mouse eggs and produced pups.
|
| 4. | Each secondary spermatocyte will form two spermatids after Meiosis II.
|
| 5. | They fertilized mouse eggs with these spermatids and produced pups.
|
| 6. | Spermatid DNA also undergoes packaging, becoming highly condensed.
|
| 7. | Alternatively they go on to differentiate into spermatocytes, spermatids and finally spermatozoa.
|
| 8. | CREM acts as a transcription factor essential for the differentiation of spermatids into mature spermatozoa.
|
| 9. | In 2016 Chinese scientists produced mouse spermatids ( precursors of sperm ) artificially from mouse stem cells.
|
| 10. | NLRP14 is found exclusively in the testes where it is expressed within spermatogonia, spermatocytes and spermatids.
