Modelling infectious disease transmission dynamics in conference environments: An individual-based approach

no code implementations17 Apr 2024 Xue Liu, Yue Deng, Jingying Huang, Yuhong Zhang, Jinzhi Lei

The global public health landscape is perpetually challenged by the looming threat of infectious diseases.

A computational scheme connecting gene regulatory network dynamics with heterogeneous stem cell regeneration

no code implementations17 Apr 2024 Yakun Li, Xiyin Liang, Jinzhi Lei

Gene regulatory network dynamics are pivotal in controlling stem cell regeneration and cell type transitions.

scRDiT: Generating single-cell RNA-seq data by diffusion transformers and accelerating sampling

2 code implementations9 Apr 2024 Shengze Dong, Zhuorui Cui, Ding Liu, Jinzhi Lei

Mathematical modeling of heterogeneous stem cell regeneration: from cell division to Waddington's epigenetic landscape

no code implementations14 Sep 2023 Jinzhi Lei

In developing the mathematical models of stem cell regeneration and tissue development, cell division is the core process connecting different scale biological processes and leading to changes in cell population number and the epigenetic state of cells.

Dynamics of cell-type transition mediated by epigenetic modifications

1 code implementation13 Sep 2023 Rongsheng Huang, Qiaojun Situ, Jinzhi Lei

Through model simulations, we demonstrate that random inheritance of epigenetic states during cell divisions can spontaneously induce cell differentiation, dedifferentiation, and transdifferentiation.

Using single-cell entropy to describe the dynamics of reprogramming and differentiation of induced pluripotent stem cells

no code implementations16 Apr 2020 Yusong Ye, Zhuoqin Yang, Jinzhi Lei

Induced pluripotent stem cells (iPSCs) provide a great model to study the process of reprogramming and differentiation of stem cells.

DNA methylation heterogeneity induced by collaborations between enhancers

no code implementations15 Feb 2020 Yusong Ye, Zhuoqin Yang, Jinzhi Lei

In this study, we developed a computational model of enhancer methylation inheritance to study the dynamics of genome-scale DNA methylation reprogramming during exit from pluripotency.

Evolutionary dynamics of cancer: from epigenetic regulation to cell population dynamics -- mathematical model framework, applications, and open problems

no code implementations19 Aug 2019 Jinzhi Lei

In this paper, we propose a general mathematical model framework for the evolutionary dynamics of cancer with plasticity and heterogeneity in cancer cells.
