The transcriptomic landscape of caudal cell mass in different developmental stages of the chick embryo.

Introduction: The caudal cell mass (CCM) is an aggregate of undifferentiated pluripotent cells and the main player in secondary neurulation. Previous studies have elucidated the dynamic fate of the multipotent cell lineages, with a recent interest in the neuromesodermal progenitors. However, a transcriptomic analysis of the CCM during secondary neurulation has not been performed yet.

Spatiotemporal contribution of neuromesodermal progenitor-derived neural cells in the elongation of developing mouse spinal cord.

Aims: During vertebrate development, the posterior end of the embryo progressively elongates in a head-to-tail direction to form the body plan. Recent lineage tracing experiments revealed that bi-potent progenitors, called neuromesodermal progenitors (NMPs), produce caudal neural and mesodermal tissues during axial elongation. However, their precise location and contribution to spinal cord development remain elusive.

Penta-fluorophenol: a Smiles rearrangement-inspired cysteine-selective fluorescent probe for imaging of human glioblastoma.

Two of the most critical factors for the survival of glioblastoma (GBM) patients are precision diagnosis and the tracking of treatment progress. At the moment, various sophisticated and specific diagnostic procedures are being used, but there are relatively few simple diagnosis methods. This work introduces a sensing probe based on a turn-on type fluorescence response that can measure the cysteine (Cys) level, which is recognized as a new biomarker of GBM, in human-derived cells and within on-site human clinical biopsy samples.
