Polyanion formulations, needle gauges and electrospray voltages used for MSC encapsulation. Polyanion formulations, needle gauges and electrospray voltages used for MSC encapsulation. Droplets of each polyanion solution were generated with each of the two needle sizes at each of the three electrospraying voltages listed. Droplets were collected into stirred chitosan solution to generate the encapsulating polyelectrolyte complex membrane

18	(1) 0.5% HA + 4% CSA	10, 12, 14
	(2) 4% CSA+ 1.5% CMC	10, 12, 14
	(3) 2% HA + 4% CSA	10, 12, 14
22	(1) 0.5% HA + 4% CSA	10, 12, 14
	(2) 4% CSA+ 1.5% CMC	10, 12, 14
	(3) 2% HA + 4% CSA	10, 12, 14
