Stem cells uniquely self-renew and maintain tissue homoeostasis by differentiating into different cell types to replace aged or damaged cells [1]. During oogenesis of Drosophila melanogaster, self-renewal of germline stem cells (GSCs) requires both intrinsic signaling mechanisms and extrinsic signals from neighboring niche cells [2]. Emerging evidence(More)
The antifreeze protein (AFP) reduces the growth rates of the ice crystal facets. In that process the ice morphology undergoes a modification. An AFP-induced surface pinning mechanism, through matching of periodic bond chains in two dimensions, enables two-dimensional regular ice-binding surfaces (IBSs) of the insect AFPs to engage a certain class of ice(More)
