Plush Cell Model

Step 11 Outer cell surface

The cell surface is covered in a variety of components; cilia, micro villi, cell surface receptors, signaling proteins, cell surface markers, transmembrane proteins, etc.

• I found a car wash mitt at a dollar store that had little chenille bits that looked to me like cilia or micro villi. So I cut several off and sewed them to the outer surface of the cell.
• I also used short strands of yarn on the cell surface. I just pulled one end of the strand through the fabric, knotted it on the back side and trimmed it to the right length.
