Hellebore pollen grain – Anastasiya Klebanovych

Donald Danforth Plant Science Center
Advanced Bioimaging Laboratory

This image showcases a pollen grain from a hellebore plant, a perennial flowering species from the Ranunculaceae family, known for its beautiful ornamental qualities. The vibrant colors in the image result from autofluorescence, a natural phenomenon where certain components of the pollen grain, such as the exine (the outer layer) and cell wall, emit light when exposed to specific excitation light. This autofluorescence allows us to see intricate details and structures within the pollen grain that are otherwise invisible to the naked eye.

Sample: Pollen grain from Hellebore plant. Sample was collected and fixed, rinsed and processed in ascending concentrations of TDE (2,2′-thiodiethanol) to ensure clearing as well as refractive index equalization across pollen components.
Label: Autofluorescence of pollen wall components

Haunted Fibers: The Ghostly Secrets of Chicken Microstructures – Ramdattu Santhapur and Dhimitraq Nikolla

University of Massachusetts Amherst
Light Microscope Facility- Institute for Applied Life Sciences

A commercially available chicken burger patty was frozen at -23°C and sectioned into 100 µm thin slices using a CryoMicrotome. This process facilitated the examination of fiber microstructures and the identification of additional ingredients present within the pre-prepared burger patty, enabling detailed structural and compositional analysis.

Sample: Food Sample (Chicken Burger Patty)
Label: Proteins were stained with FITC (green) and fats with Nile Red(Red).
Instrument: Laser Scanning Confocal Microscope with DigitalSight10 CCD (Nikon AXR-NSPARC), Plan Apo 10X 0.45-NA objective
Scale: 20µm
Image or Sample Processing Steps: LUTs adjustments on Nikon NIS Elements
