To analyze the function of lncRNAs in time-dependent processes such as chromosomal instability, a prolonged knockdown effect must be achieved. To that purpose, presented here is a protocol that uses modified antisense oligonucleotides to achieve effective knockdown in cell lines for 21 days.

Here, we describe a platform that allows noninvasive in vivo imaging of liver spheroids engrafted in the anterior chamber of the mouse eye. The workflow spans from generating spheroids from primary liver cells to transplantation into the mouse eye and in vivo imaging at cellular resolution by confocal microscopy.
