The simultaneous quantification of protein and RNA makes possible the inference of past, present, and future cell states from single experimental snapshots. To enable such temporal analysis from multimodal single-cell experiments, we introduce an extension of the RNA velocity method that leverages estimates of unprocessed transcript and protein abundances to extrapolate cell states. We apply the model to six datasets and demonstrate consistency among cell landscapes and phase portraits. The analysis software is available as the protaccel Python package.

Review history: The review history is available as Additional file 2. Peer review information: Barbara Cheifet was the primary editor of this article and managed its editorial process and peer review in collaboration with the rest of the editorial team. GG, VS, and LP were partially funded by NIH U19MH114830. Availability of data and materials: CITE-seq RNA and protein data were acquired from Gene Expression Omnibus samples GSM2695381 and GSM2695382 [31]. REAP-seq RNA and protein data were acquired from GSM2685238 and GSM2685243 [32]. ECCITE-seq control protein data were acquired from GSM3596096 [33]. ECCITE-seq CTCL protein data were acquired from GSM3596101 [33]. Due to patient privacy concerns, raw ECCITE-seq RNA data (GSM3596095 and GSM3596100) were not available, and the gene count matrices generated by velocyto were acquired by personal request. 10X Genomics 1k and 10k PBMC datasets were acquired from the 10X Genomics website [20, 21]. The datasets generated during this study are available on figshare [27,28,29,30].The Jupyter scripts used to analyze them are available on GitHub [26]. The protaccel Python package is available for installation through PyPi [24], and may be acquired as a script from GitHub [26] or Zenodo [34] under the BSD-2-Clause license.
