Summary
Chicken embryo muscle tissue survived for a year in vitro using fowl serum. This study found that cell growth and death were minimal, and plasma coagulum was unnecessary for tissue development.
Area of Science:
- Cell biology
- Developmental biology
- Tissue engineering
Background:
- Long-term in vitro cultivation of embryonic tissues is crucial for understanding cellular processes.
- Previous studies have explored various nutrient media for tissue survival.
- The role of plasma coagulum in tissue culture has been a subject of investigation.
Purpose of the Study:
- To determine the long-term viability of chick embryo breast muscle fragments in vitro.
- To investigate the effect of adult fowl serum on cell proliferation and death in cultured tissues.
- To assess the necessity of plasma coagulum for connective tissue development in vitro.
Main Methods:
- Culturing 12-day-old chick embryo breast muscle fragments in flasks.
- Utilizing frequent applications of adult fowl serum diluted with Tyrode solution as nutrient medium.
- Observing tissue survival, cell multiplication, and cell death over a one-year period.
- Comparing tissue development with and without plasma coagulum.
Main Results:
- Embryonic chick muscle tissue fragments survived for one year without transfer.
- Cell multiplication and cell death were significantly reduced in serum-cultured tissues.
- The presence of a plasma coagulum was not essential for tissue survival and development.
- Fibrinogen, prothrombin, and fibrin were not required for in vitro connective tissue fiber development.
Conclusions:
- Long-term survival of embryonic tissues in vitro is achievable with appropriate serum-based media.
- Serum alone, without plasma coagulum, adequately supports tissue maintenance and development.
- This research provides insights into the minimal requirements for in vitro tissue culture and development.

01:21Cell Culture
Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media
02:57Plant Tissue Culture
Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.
01:24Techniques for Isolation of Pure Cultures
Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...
01:17Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
01:29Need for Obtaining Pure Cultures
Pure cultures, defined as the growth of a single microorganism species isolated from mixed populations, are fundamental tools in microbiological research and practical applications. These cultures ensure genetic and physiological uniformity, allowing researchers to study microbial traits under controlled conditions.Isolation and Maintenance of Pure CulturesObtaining a pure culture involves isolating a single microbial type from a mixed sample through techniques such as serial dilutions, streak...
01:14Batch vs Continuous Culture
Fermentation is a foundational biotechnological process used to produce pharmaceuticals, biofuels, enzymes, and food additives. Among industrial strategies, batch and continuous fermentation are the two most widely applied. Although both rely on microbial conversion of substrates into desired products, they differ markedly in operation, productivity, and suitability for specific applications.Batch fermentation occurs in a closed system in which nutrient media and inoculum are added at the...
