We asked the experts to help separate fact from science fiction.
Foreskin aside, what we are seeing, however, is the rise of products advertising plant stem cells. But again, these are extracts as opposed to live plant stem cells, which simply could not survive.“Stem cell technology can have a huge impact on beauty in a medical and technological world but human stem cells cannot be used in cosmetic products,” says. “Stem cells used within the beauty industry are derived from plants – such as apples and raspberries.
But again, this is misleading. While plant-derived stem cell extracts can certainly have an anti-inflammatory and antioxidant effect, according to Dr Patel, “there is no evidence proving a clinical benefit in the way these products lead the consumer to believe – remember, plant stem cells cannot do in our body what they manage to in plants.”
“We are mammals and not plants,” agrees Holmes. “Those stem cells won’t be able to create the same level of regeneration and repair in our bodies.” Which is why most products that contain plant stem cell extracts also contain other actives or peptides.At present, human stem cells cannot survive outside lab conditions or their natural habitat, and plant stem cell extracts cannot deliver the kind of benefits stem cell technology promises.
“Growth factors are signalling proteins produced by stem cells found, for example, in the skin and used as a communication tool between the cells,” says Dr Sigrún Dögg Guðjónsdóttir, chief of research and development at. “They are recognised by our body and have a specific role to play in different organs.
At Bioeffect, Dr Dögg Guðjónsdóttir and her team use growth factors produced in barley due to their similarities to human growth factors, which “play a vital role in the production of collagen, elastin, and hyaluronic acid to maintain skin’s healthy and dense appearance”. Using this supercharged Barley EGF , their newbinds to and activates the skin’s top layer of cells, which then start to produce EGFs that activate neighbouring cells.

LINE1-Mediated Reverse Transcription and Genomic Integration of SARS-CoV-2 mRNA Detected in Virus-Infected but Not in Viral mRNA-Transfected CellsSARS-CoV-2 sequences can be reverse-transcribed and integrated into the genomes of virus-infected cells by a LINE1-mediated retrotransposition mechanism. Whole-genome sequencing (WGS) methods detected retrotransposed SARS-CoV-2 subgenomic sequences in virus-infected cells overexpressing LINE1, while an enrichment method (TagMap) identified retrotranspositions in cells that did not overexpress LINE1. LINE1 overexpression increased retrotranspositions about 1000-fold as compared to non-overexpressing cells. Nanopore WGS can directly recover retrotransposed viral and flanking host sequences, but its sensitivity depends on the depth of sequencing (a typical 20-fold sequencing depth would only examine 10 diploid cell equivalents). In contrast, TagMap enriches the host–virus junctions and can interrogate up to 20,000 cells and is able to detect rare viral retrotranspositions in LINE1 non-overexpressing cells. Although Nanopore WGS is 10–20-fold more sensitive per tested cell, TagMap can interrogate 1000–2000-fold more cells and, therefore, can identify infrequent retrotranspositions. When comparing SARS-CoV-2 infection and viral nucleocapsid mRNA transfection by TagMap, retrotransposed SARS-CoV-2 sequences were only detected in infected but not in transfected cells. Retrotransposition in virus-infected cells, in contrast to transfected cells, may be facilitated because virus infection, in contrast to viral RNA transfection, results in significantly higher viral RNA levels and stimulates LINE1 expression by causing cellular stress.
