T o improve the reconstruction of lineages from CRISPR-Cas9 mutations and scRNA-seq data, WebCRISPR gene editing (pronounced / ˈ k r ɪ s p ə r / "crisper") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be …
LinTIMaT is designed for single-cell datasets in which both edited barcode and scRNA-seq data are available from the same cell. For scGESTALT datasets, each CRISPR-Cas9 mutation event (edit) has variable length and a single event could span across multiple adjacent sites. To construct a lineage tree from … See more As mentioned in the Introduction, our method aims to reconstruct a cell lineage tree by combining two complementary types of data. For this, we defined a joint likelihood function for … See more We assume that the cell lineage tree is a rooted directed tree \({\mathscr{T}}\). The root of this lineage tree denotes the initial cell that does not contain any marker (or editing event). The leaves of this tree denote cells profiled … See more For the expression data likelihood, we model the lineage as a Bayesian hierarchical clustering (BHC)25 of the cells and used the likelihood formulation provided by BHC. … See more The first component of the likelihood function evaluates the likelihood of the cell lineage tree based on the mutation data.
