Engineering novel neuronal circuits using HI-PSCS derived neurons and microglia
The inner workings of our brain’s neural network are one of the most impactful yet simultaneously least understood natural phenomena. Previous research suggested that there might be a link to the emerging role of microglia in synaptic remodeling. However, it is still unclear as to what is the role …

Defining the essential regulators of naive human pluripotent stem cell reprogramming
Human pluripotent stem cells (PSCs) exist in two distinct states – naïve and primed, which are interconvertible. Naïve PSCs uniquely harbour several desirable properties that primed PSCs do not, including their ability to model human pre-implantation biology and developmentally-regulated epigenetic …

Metabolically rewiring pancreatic stromal cells in pancreatic cancer
… cancer-associated pancreatic stellate cells (CA-PSCs) who drive disease progression, chemoresistance and metastasis. To survive in the tumour microenvironment, CA-PSCs and PC cells undergo significant metabolic changes. A key alteration is increased expression of nutrient transporters to promote …

Pluripotency and patterning in nonhuman primate embryogenesis
… state of marmoset pluripotent stem cells (PSCs) by single-cell RNA-seq. Spatial identity mapping identified that primed marmoset PSCs correspond to the anterior EmDisc. Resetting marmoset PSCs to an earlier developmental state induced characteristic changes associated with naïve identity, …

Improving the Environmental Stability of Methylammonium-Based Perovskite Solar Cells
Perovskite solar cells (PSCs), as an emerging type of photovoltaics, have reached beyond 20% efficiency within a decade. Technoeconomic analysis suggests that PSCs are promising alternatives to the market-dominant silicon, because PSC manufacturing processes are more cost effective due to their …

The uncommon nature of point defects in organic-inorganic Perovskite solar cells
Organic-inorganic perovskite solar cells (PSCs) have shown enormous success in the past decade, increasing in power conversion efficiency from ~4% in 2009 to >22%. One of the critical properties that contributed to this success is "defect tolerance": in organic-inorganic perovskites, the majority …

Barium Oxide as an Intermediate Layer for Polymer Tandem Solar Cell
Polymer solar cells (PSCs), a member of organic solar cell family, have attracted increasing research interest. PSCs possess significant advantages over their inorganic solar cell counter parts: mechanical flexibility, light weight, low expense, and the potential to achieve roll-to-roll large-scale …

NANOGP1 as a Model to Study the Consequences of Gene Duplications on Human Pluripotency and Development
… in human naïve pluripotent stem cells (PSCs), I found that NANOGP1 is among the top 1% of the highest expressed pseudogenes. Because high expression levels of NANOG are crucial for maintaining human pluripotency, I hypothesised that a duplicated copy of this important developmental …
