Basic fibroblast growth factor: serum levels in the female.

Area of Science:

• Biochemistry
• Developmental Biology
• Endocrinology

Background:

• Basic fibroblast growth factor (b FGF) is a key angiogenic factor involved in cell growth and development.
• Understanding b FGF serum levels across different life stages and genders is crucial for insights into physiological processes.

Purpose of the Study:

• To investigate and compare serum b FGF levels in healthy females and males across various life stages.
• To determine if gender influences b FGF serum concentrations throughout human development and aging.

Main Methods:

• Serum samples were collected from healthy females (n=59) and males (n=53) across six age groups: fetuses, neonates, children, adults (proliferative/secretory phases), pregnant individuals, and the elderly.
• Enzyme immunoassay (EIA) was utilized to quantify serum b FGF concentrations.

Main Results:

• No statistically significant differences in serum b FGF levels were observed between genders.
• Serum b FGF levels were significantly elevated in fetal (cord blood) and neonatal groups compared to adult groups (p=0.01 and p=0.02, respectively).
• Within females, serum b FGF levels in neonates, children, pregnant individuals, and the elderly were comparable to adults in the proliferative phase, with only the fetal group showing a significant difference (p=0.05).

Conclusions:

• Serum b FGF levels exhibit no significant gender-based variation.
• Elevated serum b FGF concentrations are characteristic of fetal and neonatal stages, coinciding with periods of rapid growth and development.
• These findings suggest a role for b FGF in early-life development, with levels normalizing in later life stages.
