    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.

    Abstract: A laminated nonwoven fabric includes a first nonwoven fabric containing first fibers, a second nonwoven fabric containing second fibers, a third nonwoven fabric containing third fibers, and an adhesive. The second nonwoven fabric is laminated on the first nonwoven fabric, and the third nonwoven fabric is laminated on the second nonwoven fabric on an opposite side with respect to the first nonwoven fabric. The adhesive is disposed between the first nonwoven fabric and the third nonwoven fabric. An average fiber diameter of the second fibers is equal to or less than 3 ?m, and is smaller than an average fiber diameter of the first fibers. The third nonwoven fabric has a protrusion including a part of the third fibers entangled with each other on a surface facing the second nonwoven fabric. At least a part of the adhesive is disposed between the protrusion and the first nonwoven fabric.
