Pulmonary pericytes are specialized mesenchymal cells embedded within the alveolar capillary basement membrane. They envelop capillaries and have processes forming focal contact with endothelial cells. Pericytes in the lung help maintain structural integrity and contribute to vascular repair after lung injury. Lung pericytes can sense danger signals and amplify inflammatory responses by elaborating cytokines. Disruption in pericyte-endothelial cell interaction (PDGF-PDGFRβ signaling axis) can lead to abnormal vasculogenesis in early embryonic development.
Why choose Human Pulmonary Pericytes from AcceGen?
Human pulmonary pericytes are derived from healthy human lungs with fully consented donors using AcceGen’s advanced technology. Cells are immediately cryopreserved to ensure the best viability. Each vial contains more than 5×10^5 cells in 1ml volume. Human pulmonary pericytes are quality tested with the expression of platelet-derived growth factor-ß (PDGFRß) and α-smooth muscle actin by immunofluorescence.

Pulmonary pericytes are specialized contractile cells found wrapped around the endothelial cells of capillaries and venules in the lungs. They play a crucial role in maintaining blood vessel stability, regulating blood flow, and supporting the endothelial cells.
The primary function of pulmonary pericytes is to provide structural support to blood vessels, regulate blood-brain barrier integrity, influence blood flow, and participate in the repair and regeneration of the vasculature in the lungs.
Yes, dysfunction of pulmonary pericytes is closely related to pulmonary diseases such as pulmonary hypertension, fibrosis, and chronic obstructive pulmonary disease (COPD). Their malfunction can lead to abnormal vascular remodeling, inflammation, and tissue scarring, exacerbating the progression of these conditions.
Pulmonary pericytes interact with endothelial cells through direct physical contact and paracrine signaling. These interactions are essential for blood vessel stability, regulation of permeability, and angiogenesis.
Key signaling pathways involved in pulmonary pericyte function include the PDGF (platelet-derived growth factor) pathway, TGF-β (transforming growth factor-beta) pathway, and Notch signaling. These pathways regulate pericyte proliferation, migration, and differentiation.
