Could you share the cell types in GAGE-seq data?

Hi, tianming
I am reading your paper 'GAGE seq concurrent profiles multi-scale 3D genome organization and gene expression in single cells'. This is a very meaningful job that provides high-quality sequencing data. But when I tried to use this data in my method, I couldn't find any annotation files about cell types. Could you share the cell types? It will be very helpful to me. Thank you!
