Monitoring peripheral nerve degeneration in ALS by label-free stimulated Raman scattering imaging

Nature Communications, 2016
Sensitive and label-free imaging methods to visualize nerve degeneration are currently lacking. Here authors show that stimulated Raman scattering (SRS) microscopy can be used to monitor peripheral nerve degeneration in mouse models of amyotrophic ...

Proton MR Spectroscopy of Neural Stem Cells: Does the Proton-NMR Peak at 1.28 ppm Function As a Biomarker for Cell Type or State? [PDF]

, 2011
Recently, a peak at 1.28 ppm in proton magnetic resonance spectroscopy (^1H-MRS) of neural stem cells (NSCs) was introduced as a noninterventional biomarker for neurogenesis in vivo. This would be an urgently needed requisite for translational studies in

Stem-cell ecology and stem cells in motion

Blood, 2008
Abstract This review highlights major scientific developments over the past 50 years or so in concepts related to stem-cell ecology and to stem cells in motion. Many thorough and eloquent reviews have been presented in the last 5 years updating progress in these issues.

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Improving cellular fitness of human stem cell-derived islets under hypoxia

Nature Communications
Stem cell-derived islet cell therapy can effectively treat type 1 diabetes, but its efficacy is hindered by low oxygen supply post-transplantation, particularly in subcutaneous spaces and encapsulation devices, leading to cell dysfunction.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Lack of correlation of stem cell markers in breast cancer stem cells [PDF]

, 2014
BACKGROUND: Various markers are used to identify the unique sub-population of breast cancer cells with stem cell properties. Whether these markers are expressed in all breast cancers, identify the same population of cells, or equate to therapeutic ...

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Generation of pancreatic β cells for treatment of diabetes: advances and challenges

Stem Cell Research & Therapy, 2018
Human embryonic stem cells (hESC) and induced pluripotent stem cells (hiPSC) are considered attractive sources of pancreatic β cells and islet organoids.

Disruption of SETD3‐mediated histidine‐73 methylation by the BWCFF‐associated β‐actin G74S mutation

FEBS Letters, EarlyView.
The β‐actin G74S mutation causes altered interaction of actin with SETD3, reducing histidine‐73 methylation efficiency and forming two distinct actin variants. The variable ratio of these variants across cell types and developmental stages contributes to tissue‐specific phenotypical changes. This imbalance may impair actin dynamics and mechanosensitive
