“…In this work we provide insights into callus features, having specific gene expression patterns that sustain high proliferation rate, independently from maintaining the potential to initiate all lineages of the mature organism. It is generally accepted that mammalian embryonic stem (ES) cells maintain pluripotency through retaining globally open chromatin state by basal transcription, to confer transcriptional competence for developmental programs (54, 55). We identify related strategy in callus, of keeping lineage-affiliated genes transcriptionally active, enabling the rapid response to signals, without the needs to go through the complex process of transcription.…”

“…Thus far, the generally accepted mechanism is the LIF‐dependent activation of JAK2, which conveys its signals through STAT3 to the nucleus, leading to the expression of the core pluripotency gene network 58,59 . In addition, epigenetic regulation is an indispensable factor of pluripotency, by which undifferentiated/pluripotent ESC gene expressions are maintained in their open DNA/chromatin structures accessible for transcription activators 60,61 . Therefore, we postulated that the LIF‐JAK2‐STAT3 canonical pathway should be linked to the epigenetic regulation associated with the undifferentiated/pluripotent gene transcriptions.…”

In this study, we demonstrated that LIF treatment in mESC cultures establishes the active epigenetic signature associated with DNA/histone demethylation in the promoter regions of the core pluripotent genes, and that the LIFinduced epigenetic regulation is mediated by JAK2, but not by STAT3.…”

“…On the contrary, as cells commit to the different lineages, the condensed heterochromatin starts to predominate preventing the expression of genes characteristic of unrelated cell types [19]. Hence, the overall goal of the reprogramming process is to erase the epigenetic marks characteristic of the differentiated cells yielding a pristine status comparable to that of the pluripotent cell.…”
