Scientific evidence was given by Ng et al. (1986) in Hong Kong, suggested that Blood Nest might possess immunoenhancing effect by aiding cell division of immune cells. In 1987, other scientific evidence was published by Kong et al, demonstrated an epidermal growth factor (EGF) that stimulated the DNA synthesis in 3T3 fibroblast in a dose dependent manner in vitro. EGF is a 6,000 Da polypeptide hormone produced by glands of the gastrointestinal tract, namely the salivary and Brunner's glands. It appears to play a crucial role in major normal cellular processes such as proliferation, differentiation and development. It may offer a rationale for the medicinal use of edible Blood Nest in ageing resistance. Since the receptor for EGF is highly expressed in a number of solid tumors, including breast, head-and-neck, non-small-cell lung, renal, ovarian and colon cancer, people are worried about a possibility to induce tumor progression and to resist chemotherapy/radiation treatment in tumor cells; in consequence, suggest that cancer patients should avoid Blood Nest. However, there is no evidence supporting this suggestion. Scientific evidence for its efficacy is still limited.
