Using a Hemacytometer to Count Cells

2023
Many biomedical experiments require manipulation of a known quantity of cells, in order to achieve accurate, reproducible, and statistically-relevant data. Therefore, learning how to count cells is a particularly essential technique for any successful biomedical scientist. The most common way to count cells is by using a hemacytometer - an instrument that bears two laser-etched grids, which aid in the enumeration of an aliquot cells under a simple light microscope. This data can then be used to...

Here, we describe protocols for the preparation of trans-cyclobutane fused cyclooctenes (tCBCO), their polymerization to prepare depolymerizable olefinic polymers, and the depolymerization of these polymers under mild conditions. Additionally, protocols for the preparation of depolymerizable networks and compression molding of rigid linear plastics based on this system are described.

Lipid polyesters constitute the structural components of two cell wall modifications, the plant cuticle and suberin-containing diffusion barriers. In this video, we describe a method to depolymerize cutin from whole delipidated leaves. The method can be applied to investigating mutants compromised in either cutin or suberin biosynthesis.

The carbon-carbon double bond provides the reactive site for free-radical polymerization. Initiators generate radicals that enable monomer units to link into polymer chains, allowing HEMA-based formulations to become hydrophilic polymers or crosslinked materials. This reaction pathway is central to converting the liquid monomer into engineered structures with useful mechanical and transport properties.
The hydroxyl group increases water compatibility and provides a site for chemical modification or network formation. Consequently, it influences how the resulting material interacts with aqueous environments while also supporting additional structural control. Engineers can use this functionality when designing hydrogels, coatings, or other materials that require both processability and hydrophilicity.
Initiator selection, comonomer incorporation, and crosslinking conditions are key variables. Adjusting them can change swelling, stiffness, permeability, and durability in the final material. These variables allow engineers to balance water uptake against structural performance rather than treating hydrophilicity as an isolated property, which is important when a material must operate reliably in demanding applications.
Crosslinking conditions influence whether polymer chains form a network and help determine the resulting balance of swelling, stiffness, permeability, and durability. Greater control over network formation supports targeted performance in crosslinked materials and hydrogel systems. The selected conditions therefore connect the polymerization process to the practical behavior required for a specific engineering design.
HEMA monomer-based materials are used in contact lenses, dental composites, coatings, and hydrogel systems. These applications benefit from the combination of water compatibility and controllable material performance. By modifying initiators, comonomers, and crosslinking conditions, engineers can adapt the material’s swelling, stiffness, permeability, and durability to different functional requirements.
Its hydroxyl group supports water compatibility, while polymerization and network formation enable control over mechanical and transport behavior. That combination is valuable for contact lenses and hydrogel systems, where hydrophilicity must coexist with usable stiffness, permeability, and durability. HEMA-based formulations therefore provide an engineering route to balance aqueous interaction with structural function.
