Peer review has been under siege for years. Consider it as one cost of the on-going commodification/mercantilisation of science.
The referenced article was:
Cellular functions of spermatogonial stem cells in relation to JAK/STAT signaling pathway by Xinyu Guo, Liang Dong, and Dingjun Hao in
Frontiers in Cell and Developmental Biology (Molecular and Cellular Reproduction) Volume 11, 13 Feb 2024 -

Even the accreditations are somewhat garbled. All authors are connected with the 'Department of Spine Surgery' of Xi'an Honghui Hospital in Shaanxi. Xinyu and Dingjun also have positions at Jiaotong University in Xi'an.
Not surprisingly, the Chief Executive Editor of Front. Cell Dev. Biol. approved the retraction of this article on 16 February.
