Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

In Vitro Propagation of Narcissus1

HortScience, 1980
Abstract Tazetta narcissus ‘Geranium’ and large-cupped ‘Fortune’ were propagated from tissue cultures. Cultures of young flower stalks of ‘Geranium’ produced many adventitious buds on a culture medium supplemented with 5mg/liter 6-benzylamino purine (BA) plus 1mg/liter naphtaleneacetic acid. (NAA).
