Published on: April 12, 2021

  • Employed rotary cultures to generate 3D aggregate structures.
  • Analyzed cell differentiation using immunohistochemistry, Western blot, and reverse transcription-polymerase chain reaction.

    • Main Results:

    • Retinal progenitors formed aggregates in rotary culture, increasing in size over 10 days.
    • Confirmed photoreceptor differentiation via upregulation of rhodopsin and AaNat.
    • Demonstrated differentiation into amacrine (tyrosine hydroxylase), ganglion (thy 1.1), and cone (calbindin, GNB3) cells.

    Conclusions:

    • 3D rotary culture of retinal progenitors promotes cell-cell interaction and retains differentiation potential.
    • This multipotent cell line can generate diverse retinal cell types, showing promise for retinal tissue engineering.
    • Engineered retinal constructs from these progenitors may be valuable for future transplantation therapies.
