An Introduction to Stem Cell Biology
0 Views •
2023
Cells that can differentiate into a variety of cell types, known as stem cells, are at the center of one of the most exciting fields of science today. Stem cell biologists are working to understand the basic mechanisms that regulate how these cells function. These researchers are also interested in harnessing the remarkable potential of stem cells to treat human diseases. Here, JoVE presents an introduction to the captivating world of stem cell biology. We begin with a timeline of landmark...

This video presents synthetic biology and its role in bioengineering. Synthetic biology refers to the methods used to genetically modify organisms in order to make them capable of producing large quantities of a product. This product could be a protein that the cell already makes or a new protein that has been encoded in a newly-inserted DNA sequence. Here, we discuss how an organism's genetic material is modified using transformation or transfection. Then, the process is shown in the...

In this video, we show a procedure for an accurate biolistic delivery of reagents into live tissue with a novel miniature gene gun. We are knocking down the expression of the axon guidance molecule Netrin in leech embryos by delivering molecules of dsRNA into the ventral body wall and ganglia of single segments.

Biological Effects of Radiation

2020
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
FAQs
Their clinical effects arise from selective interactions with defined biological targets, including receptors, enzymes, and immune signals. By binding or influencing these targets, a biologic can block a disease-driving pathway, replace a missing protein, stimulate protective immunity, or alter an abnormal immune response. This target specificity helps connect the medicine’s molecular action to a particular disease mechanism.
These product types support different therapeutic strategies. Proteins can replace substances the body lacks, while antibodies can act against selected targets or immune signals. Vaccines stimulate protective immunity, and gene-based treatments address disorders through genetic approaches. Their distinct biological functions allow clinicians to select therapies according to whether treatment requires replacement, pathway blockade, immune stimulation, or gene modification.
Biologic medicines have complex molecular structures, so their identity and behavior depend on controlled biological production as well as the product itself. Recombinant cells can manufacture them under controlled conditions, but the resulting medicines still require careful characterization. This complexity distinguishes them from many small-molecule drugs and makes consistent production and evaluation central to their clinical use.
Because these therapies are biologically derived and may interact closely with immune pathways, clinical use requires monitoring for immune reactions. Such reactions can influence how safely a patient receives treatment and may affect the overall therapeutic experience. Monitoring is therefore part of responsible clinical management, particularly when a medicine is designed to modify abnormal immune responses or stimulate protective immunity.
Development requires controlled production, careful characterization, appropriate manufacturing, and suitable storage. Recombinant cells may produce the therapeutic product under controlled conditions, after which the medicine must be evaluated and handled consistently. These steps support reliable clinical use by addressing the complexity of biologic structures before treatment reaches patients.
Manufacturing and storage matter because biologic medicines depend on complex structures and controlled biological production. Conditions that do not preserve the product appropriately could compromise the medicine’s intended clinical role, making careful handling essential. For this reason, clinical practice considers not only the treatment’s target and mechanism but also how it is produced, characterized, stored, and monitored.
Biologic medicines have applications across cancer, autoimmune disease, infectious disease, and genetic disorders. Their clinical value reflects the range of mechanisms they can support: blocking disease-driving pathways, modifying abnormal immune responses, stimulating protective immunity, replacing missing proteins, or addressing genetic disorders. This breadth makes them relevant when conventional approaches cannot provide the required biological effect.
