Characterizing the temporal dynamics of gene expression in single cells with sci-fate

Project description:Gene expression is a dynamic process on multiple scales, e.g. the cell cycle, response to stimuli, normal differentiation and development, etc. However, nearly all techniques for profiling gene expression in single cells fail to directly capture these temporal dynamics, which limits the scope of biology that can be effectively investigated. Towards addressing this, we developed sci-fate, a new technique that combines S4U labeling of newly synthesized mRNA with single cell combinatorial indexing (sci-), in order to concurrently profile the whole and newly synthesized transcriptome in each of many single cells. As a proof-of-concept, we applied sci-fate to a model system of cortisol response, and characterized expression dynamics in over 6,000 single cells. From these data, we quantify the dynamics of the cell cycle and of glucocorticoid receptor activation, while also exploring their intersection. We furthermore use these data to develop a framework for estimating cell state transition probabilities, and to identify factors whose dynamic expression potentially regulates these transitions. The experimental and computational methods described here may be broadly applicable to quantitatively characterize cell state dynamics in in vitro systems.

Transcriptional study of the temporal evolution after severe traumatic spinal cord injury (SCI) and neural progenitor cells (NPCs)-transplantation intervention.

Project description:The present study is intended to disclose the transcriptional profile of the temporal evolution through the different stages after SCI as well as the molecular processes underlying the NPC based-therapy in order to transcriptionally characterize its therapeutical mechanism. This transcriptional profile analysis of total RNA samples from spinal cord homogenates of adult rats (Sprague Dawley) provides tissular (tought not cell-type specific) information of the critical time points after the injury from 1 to 8 weeks (acute, sub-acute and early-chronic and late-chronic stages) which conferred a wide temporal coverage making it ideal for studying the temporal dynamics of SCI. Furthermore, we have evaluated the impact of intramedullary acute or subacute transplantation of NPCs over the transcriptional regulation of the spinal cord tissue in order to define the functional outcomes of the NPCs therapy.

Flexible and scalable control of T cell memory by a reversible epigenetic switch (sci-fate-seq)

Project description:In this study, we use a minimal ex vivo culture system to track CD8 T cell differentiation at the single cell and clonal lineage level during activation. To characterize early heterogeneity in memory and effector differentiation in this system, we subjected cells to temporally-resolved single-cell transcriptomic profiling using sci-fate-seq (Cao et al., Nature Biotech, 202).

The dynamics of Atm signalling dictate cellular fate decisions after DNA damage

Project description:DNA damage activates diverse cellular responses â€“ either protective or deleterious â€“that ultimately promote or inhibit proliferation. How the distinct responses conferring crucial cell fate decisions are chosen is unclear. Using a systems approach, we demonstrate that the dynamic features of Atm dependent DNA double-strand break (DSB) signalling response dictate cellular outcome. Combining temporal phosphoproteome and nascent transcriptome analyses after low or high DNA-damage-load, we discovered that some responses, such as Tp53 activation, have an activation threshold and others arise independently of DNA-damage-load. Using DSB repair deficient cells, we show that persistent DSBs alter the kinetics â€“ but not the amplitude â€“ of Atm signalling. Thus, we demonstrate that pathway choices are dictated by the signalling dynamics and hence cell fate decisions are responsive to DNA-damage-load and repair capacity of the cells.
