  • Publication number: 20220049214
    Abstract: Efficient stem cell delivery into biomaterials using capillary driven encapsulation are disclosed herein where stem/progenitor and/or tissue specific cells are rapidly and efficiently seeded via capillary driven encapsulation into a porous scaffold for cell delivery in the skin or any other organ. The rapid capillary force approach maximizes both seeding time and efficiency by combining hydrophobic, entropic and capillary forces to promote active, ‘bottom-up’ cell engraftment. This methodology uses micro domain patterned biopolymers in a porous dry gel to generate capillary pressure to move a viscous stem cell mix from a hydrophobic reservoir into the polymer matrix to promote active cell seeding within the entire gel volume.
