Semiquantitative assessment of graft survival per pig and time point.

Pig ID no.	Survival	Donor cells	Distribution
211	10 days	+++	SRS, retina, RPE
208	11 days	++	SRS, retina
202	12 days	+++	SRS, retina
213	13 days	+	SRS
207	28 days	−

Abbreviations: +++: many cells present, ++: moderate numbers of cells, +: a few cells, −: no cells, SRS: subretinal space, RPE: retinal pigment epithelium.
