What are the primary sources of growth factors in living organisms?
Best insight from top research papers
Growth factors in living organisms are primarily produced by the organism's own tissues, including epithelia, neural, lymphoid, muscle, blood vessels, lymphatic system, myeloid, erythroid, and hepatic systems . These growth factors play a crucial role in regulating cell proliferation, differentiation, movement, survival, and self-renewal of stem cells within the tissues . They are also involved in controlling inflammatory, wound-healing, and antiviral responses . In addition to tissue-specific production, growth factors can also be produced by mesenchymal cells and endothelial cells, such as hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) . Furthermore, growth factors can be used as therapeutics for tissue regeneration and disease treatments, and their delivery to specific cells or tissues is facilitated by various biomaterials . Overall, growth factors are essential for cell communication and play a vital role in the growth and development of living organisms .

What are the sources of probiotics?5 answersProbiotics can be sourced from various traditional fermented products such as dairy products, vegetables, and soy products. Other sources include soil, milk, curd, and non-dairy fermented foods and beverages. Unconventional sources like fruits, vegetables, flowers, and ethnic fermented beverages also contain microorganisms with probiotic properties. The major microorganisms used as probiotics are bacteria from the genera Lactobacillus, Lactococcus, Streptococcus, and Bifidobacterium, as well as yeasts. These sources provide living microorganisms that confer health benefits when consumed as dietary supplements or incorporated into food products.
What are some good sources of protein?5 answersProteins are essential for building muscle strength and optimizing athletic performance. They can be obtained from both animal-based and plant-based sources. The body requires a sufficient quantity of amino acids from a good source of protein for muscle synthesis and various metabolic processes. However, excessive protein consumption can have negative effects on the kidneys, calcium levels, bone health, and cardiovascular health. In the US, protein sources include meat, fish, eggs, dairy products, and beans. The Mediterranean dietary pattern emphasizes reduced intake of animal-based foods and favors fish as a protein source due to its beneficial fatty acid composition. Insects and algae are emerging as potential protein sources, although consumer acceptance and logistical challenges remain. In terms of protein quality, certain insect species and lesser mealworm are considered good sources for different age groups. Consuming a variety of plant-based proteins ensures access to all essential amino acids.
What are sources of protein?5 answersProteins are essential for the human body and can be obtained from various sources. Traditional sources of food proteins include milk, meats (including poultry and fish), eggs, cereals, legumes, and oilseeds. However, due to the increasing world population, there is a need to develop nontraditional protein sources to meet future demands. Plant-based proteins, such as those from cereals and legumes, are more sustainable but may be incomplete in their amino acid profile. Alternative protein sources like wheat protein, fish protein, chicken products, eggs, and processed red blood cells also provide essential and nonessential amino acids. Specialized protein sources from algae and fungi are being introduced into food products. For athletes, protein intake is crucial for muscle strength and athletic performance, and it can be obtained from both animal-based and plant-based sources.
What are the sources of collagen production?4 answersCollagen can be obtained from various sources. Animal-derived collagen is currently the most common source, with collagen extracted from fish skins, bovine and porcine skins, and organic matter of skin, bones, and tendons. However, animal-derived collagen has limitations such as immunogenicity, batch-to-batch variation, and pathogenic contamination. There is a growing interest in obtaining collagen from waste materials, such as non-tanned waste from leather production, as a sustainable and natural alternative. Recombinant collagen is also a potential solution, although industrial-scale production of correctly post-translationally modified recombinant human collagen has not yet been achieved. Overall, collagen can be sourced from animals, waste materials, and through recombinant expression systems.
What is the sources of biogenic amines?4 answersBiogenic amines in food and beverages are mainly formed due to the presence of proteins and/or free amino acids, which serve as substrates for microbial or natural enzymes with decarboxylation or amination activity. Dairy products can also be a source of biogenic amines, as they provide a suitable environment for their production and accumulation. Bacteria play a significant role in the decarboxylation of amino acids, resulting in the production of biogenic amines in various foods. Improper storage of food can lead to the formation of biogenic amines through microbial decarboxylation of amino acids. In alcohol-free beverages, biogenic amines can be synthesized by enzymes naturally present in raw materials or by microorganisms added during the transformation process.
What are the natural sources of enzymes?5 answersEnzymes are natural proteins produced by living cells and can be found in a wide range of species, including animals, plants, and microorganisms. Microorganisms, such as bacteria, yeasts, and fungi, are particularly advantageous as a source of enzymes due to their lower production costs, wide range of physical and chemical characteristics, and the ability to manipulate their genetic makeup. Enzymes extracted from edible plants and the tissues of food animals have also been used for centuries in food manufacturing processes. Additionally, enzymes can be produced through the fermentation of fresh vegetable and fruit waste, resulting in bio enzymes that have proven to be effective in domestic and agricultural applications. The use of microbial enzymes in industrial processes is increasing, as they offer a reliable and easily controlled supply of raw material, as well as a wide range of biochemical diversity.
