We provide different tools and methods in Julia to
(1) simulate, explore and analyse the landscape for a given model and
(2) visualise the landscape of certain genes or gene combinations (after applying dimensionality reduction) given a single-cell data set.
The Waddington or epigenetic landscape provides a theoretical framework for cell development and differentiation. A figure and citation from Waddington's original paper [1]:
The cell development process can be described by a general stochastic model.
How do we get from a stochastic system to an epigenetic landscape?
- Some stochastic systems can be expressed in terms of a potential.
- Potential functions are similar to epigenetic landscapes.
Different dimensionality reduction methods are used, ia linear methods such as PCA, SVD, PPCA as well as non-linear methods such as Kernel PCA, MDS, ICA.
