Porcine Spontaneously Immortalised Adipocyte Derived Stem Cells

Spontaneously immortalised stem cells derived from porcine primary adipose tissue. These cells were treated using a non-integrative, non-GMO method to induce spontaneous immortalisation. The cells have a rapid (<17 hours) average population doubling time, can be adapted to adherent and suspension growth conditions in serum and serum free media formulations. They are easy to handle, and are suitable for enabling technology discovery and scalable cultivated fat product development.

Cell Characterization

qPCR to asses fold change of markers indicating functional immortalisation of the psiADSCs. MK67 is a marker fo proliferation. PRIM2 is a marker of DNA replication. Caspase 3 is a marker of cell apoptosis. SQS is a checkpoint inhibitor. SMC3 is a maker of structural maintenance and cell cycle. And MCM2 is a marker of gene replication and cell cycle.



Following enzymatic digestion of fresh porcine abdominal adipose tissue, cells were cultured on treated cell culture plastic for 2 passages to isolate and expand the ADSC population. ADSCs were spontaneously immortalised using two methods. Following immortalisation psiADSCs retain their capacity for adipogenic differentiation. psiADSCs are cultured in high glucose DMEM containing 10% FBS, but can be adapted to serum free media formulations.

Differentiation Characterization

Morphology of expanded psiADSCs (left) and differentiated psiADSCs after 10 days of differentiation protocol (right). Accumulation of lipid molecules can be seen in the differentiated cells.

Oil-O-red staining of differentiated psiADSCs. Cells were fixed for 15 minutes in 4% PFA solution and stained for 30 minutes in oil-O red solution at 10 days after differentiation protocol was initiated. Red staining indicates lipids in all cells, but clusters of lipids can be seen in the differentiated cells. Differentiated cells from immortalisation method 1 (left) and immortalisation method 2 (right).
