Abstract

Spermatogonial stem cells (SSCs) are the only stem cells in the body that transmit genetic information to the next generation. The long-term propagation of rodent SSCs is now possible in vitro, and their genetic modification is feasible. However, their differentiation into sperm is possible only under in vivo conditions. Here we show a new in vitro system that can induce full spermatogenesis from SSC lines or any isolated SSCs. The method depends on an organ culture system onto which SSCs are transplanted. The settled SSCs form colonies and differentiate up into sperm. The resultant haploid cells are fertile, and give rise to healthy offspring through micro-insemination. In addition, the system can induce spermatogenesis from SSCs that show spermatogenic failure due to a micro-environmental defect in their original testes. Thus, an in vitro system is established that can be used to correct or manipulate the micro-environmental conditions required for proper spermatogenesis from murine SSC lines.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Niche aging is a major contributor to the functional decline of GSCs.

    “Moreover, consecutive transplantation of spermatogonial stem cells to the testes of young male mice was sufficient to maintain stem cell function for extended periods of time, underscoring a major role of aging of the niche in GSC functional decline and suggesting the potential for reversing aging phenotypes by targeting the niche155.”
  • Repeatedly transplanting spermatogonial stem cells into young mouse testes kept stem cell function going for long periods.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
