Description
Mesenchymal cells are loosely organized embryonic cells that give rise to connective tissues, bone, cartilage, and fat, and their controlled proliferation is fundamental to development and tissue homeostasis. The Gene Ontology term GO:0002053, positive regulation of mesenchymal cell proliferation, captures the biological processes that activate or increase the rate or extent of mesenchymal cell proliferation. Understanding this process is critical because aberrant mesenchymal proliferation underlies diverse pathologies, from premature ovarian insufficiency to leukemia and ectopic bone formation [1, 3, 4].

What Happens During positive regulation of mesenchymal cell proliferation?
Initiation by Growth Factors and Signaling Cues
In simple terms: Signals from outside the cell tell mesenchymal cells to start dividing.
Positive regulation begins when extracellular cues, such as growth factors and cytokines, bind to receptors on mesenchymal cells and activate intracellular signaling cascades. For example, Hippo signaling pathway components regulate mesenchymal stem cell-derived exosome effects on ovarian function and proliferation. GDF11 and TET2 mutual regulation prevents senescence and supports mesenchymal stem cell proliferation.
Cell Cycle Entry and Progression
In simple terms: The cell's internal clock is pushed forward to enter and complete division.
Once activated, signaling pathways drive cell cycle entry and progression. Cell cycle-dependent expression of BK channels in human mesenchymal endometrial stem cells influences their proliferation. Hydroxyurea-induced senescent mesenchymal stromal cells inhibit bystander cell proliferation of JAK2V617F-positive erythroleukemia cells, linking cell cycle status to paracrine regulation.
Metabolic and Autophagic Modulation
In simple terms: The cell's recycling and energy systems are adjusted to support growth.
Autophagy plays a role in bone marrow mesenchymal stem cell proliferation and differentiation into neurons. Metformin potentiates immunosuppressant activity and adipogenic differentiation of human umbilical cord-mesenchymal stem cells, indicating metabolic modulation of proliferation and differentiation.
Transition to Differentiation or Transit-Amplifying States
In simple terms: Dividing mesenchymal cells can either keep dividing or specialize into other cell types.
Regulation of mesenchymal stem to transit-amplifying cell transition in the continuously growing mouse incisor demonstrates that positive regulation of proliferation is tightly linked to differentiation decisions. Single-cell RNA sequencing identified PD-L1+ mesenchymal stem cells with enhanced immunomodulatory capacity and alleviated ectopic new bone formation in ankylosing spondylitis, showing heterogeneity in proliferative and functional states.

How Is positive regulation of mesenchymal cell proliferation Regulated?
Positive regulation of mesenchymal cell proliferation is controlled by multiple layers of regulation, including Hippo signaling pathway components that modulate exosome effects on ovarian function, GDF11 and TET2 mutual regulation that prevents senescence, and autophagy that influences bone marrow mesenchymal stem cell proliferation and differentiation. Additionally, cell cycle-dependent BK channel expression in endometrial stem cells affects proliferation, and metabolic modulators such as metformin alter adipogenic differentiation and immunosuppressive activity.

Premature Ovarian Insufficiency
Human umbilical cord mesenchymal stem cell-derived exosomes improve ovarian function and proliferation in premature ovarian insufficiency by regulating the Hippo signaling pathway. This links positive regulation of mesenchymal cell proliferation to reproductive disorders.
Leukemia and Myeloproliferative Neoplasms
Hydroxyurea-induced senescent peripheral blood mesenchymal stromal cells inhibit bystander cell proliferation of JAK2V617F-positive human erythroleukemia cells, suggesting that mesenchymal cell proliferation regulation impacts leukemia progression.
Ankylosing Spondylitis and Ectopic Bone Formation
Single-cell RNA sequencing identified PD-L1+ mesenchymal stem cells with enhanced immunomodulatory capacity and alleviated ectopic new bone formation in ankylosing spondylitis, implicating mesenchymal proliferation in pathological bone formation.
Mesenchymal Stem Cell Senescence
GDF11 and TET2 mutual regulation prevents senescence of mesenchymal stem cells, and dysregulation of this axis may contribute to age-related decline in regenerative capacity.
