Cell-mediated and neural control of morphostasis

Area of Science:

• Cell Biology
• Developmental Biology
• Immunology

Background:

• Morphostasis is crucial for homeostasis and organismal existence, involving the maintenance of differentiated cell states.
• Immunoglobulin-gene superfamily (IGSF) domains are increasingly recognized for their role in non-immune cellular control.
• A novel tissue control system (TCS) is proposed to regulate tissue cell differentiation via IGSF domains.

Purpose of the Study:

• To propose a novel epigenetic mechanism for morphostasis control.
• To elucidate the role of the tissue control system (TCS) and immunoglobulin-gene superfamily (IGSF) domains in maintaining tissue differentiation.
• To explain how cell differentiation is arrested and maintained in adult tissues.

Main Methods:

• Theoretical framework development based on existing evidence.
• Epigenetic modeling of morphostasis establishment.
• Hypothesized role of cell surface markers and signaling pathways.

Main Results:

• Morphostasis is established epigenetically during an early adaptive period, coinciding with immunocompetence.
• The TCS encodes cell surface markers as stop-signals (SS) to prevent further differentiation.
• A stop-effect (SE) is maintained by the TCS, with hormones potentially modulating SS recognition.

Conclusions:

• The TCS, utilizing IGSF domains, provides a cell-mediated control mechanism for morphostasis.
• Epigenetic regulation and cell surface marker recognition are key to maintaining differentiated states.
• Hormonal influences can modulate the stop-signal, potentially allowing for controlled cellular changes.
