新冠疫情期間,在壓力和新冠后遺癥的雙重影響下,人們的發(fā)際線比平時(shí)更快后移。許多人在感染新冠病毒的兩三個(gè)月后,脫發(fā)問題開始加重,而且這種情況會(huì)持續(xù)6至9個(gè)月。
一家硅谷生物科技初創(chuàng)公司dNovo開發(fā)了一種有望解決這個(gè)問題的方案。該公司稱,其成功地將脂肪細(xì)胞或血細(xì)胞等普通細(xì)胞重新編程為人體毛囊。
dNovo能夠用幾滴血制造出可以用于生發(fā)的定制毛囊干細(xì)胞。據(jù)稱,這些細(xì)胞能夠逃過免疫系統(tǒng)攻擊,避免排斥反應(yīng)。
dNovo的創(chuàng)始人是曾經(jīng)就讀于斯坦福大學(xué)(Stanford University)的生物學(xué)家埃內(nèi)斯托·盧揚(yáng)。該公司在2019年憑借一項(xiàng)正在申請(qǐng)專利的技術(shù)首次取得突破,該技術(shù)可以利用不同人類細(xì)胞再生毛囊干細(xì)胞。這個(gè)過程分為五個(gè)步驟:采集細(xì)胞,對(duì)細(xì)胞重新編程,培養(yǎng)新生發(fā)細(xì)胞,將新生發(fā)細(xì)胞移植到頭皮,然后等待一到三個(gè)月后長出頭發(fā)。
這項(xiàng)技術(shù)仍然需要許多年時(shí)間才能夠用于人類。目前,該技術(shù)的效果僅在老鼠身上得到了證明。
盧揚(yáng)告訴《財(cái)富》雜志:“我們目前仍然在臨床前開發(fā)階段。我們展示了該技術(shù)在實(shí)驗(yàn)小鼠身上的效果,這讓我們感到非常興奮。”
他補(bǔ)充道:“我們希望最終可以在人體試驗(yàn)中證明該技術(shù)的效果,并將我們的產(chǎn)品投入商業(yè)應(yīng)用,但目前還處在初級(jí)階段。”
dNovo并非唯一一家在實(shí)驗(yàn)室培育生發(fā)細(xì)胞的公司。另外一家生物科技公司Stemson Therapeutics在2021年7月融資1500萬美元,致力于“以新型細(xì)胞再生技術(shù)將患者人體細(xì)胞再生成毛囊”,找到解決脫發(fā)問題的辦法。

Stemson Therapeutics正是采用了這個(gè)配方。該公司稱它最早“利用iPSC生成新毛囊治療脫發(fā)。”該公司的技術(shù)尚未投入商業(yè)應(yīng)用。

Hairlines have receded faster than usual during the pandemic due to both stress and the aftereffects of COVID 19. After a coronavirus infection, many people experience increased hair shedding starting two to three months after becoming sick, and continuing for a total of six to nine months.
A Silicon Valley biotech startup, dNovo, has developed a possible solution for this problem. The company claims it has managed to reprogram ordinary cells, like fat or blood cells, into human hair follicles.
Starting with a few drops of blood, dNovo can produce customized hair stem cells that can be used to?create new hair. The cells are said to be able to evade any immune system response that would reject them.
DNovo, founded by Stanford University–trained biologist Ernesto Lujan, had its first breakthrough in 2019 with a patent-pending technology that regenerates various kinds of human cells into hair stem cells. The process requires five steps: collecting cells, reprogramming them, growing the new hair-producing cells, adding those hair-producing cells to human scalps, and finally waiting one to three months for the hair to grow.
The technology is years away from being ready for humans. For now, its effectiveness has been shown to work only on mice.
“We are currently in the preclinical stage of development,” Lujan told Fortune. “We have shown the results in laboratory mice and are very excited with those.”
He added, “We hope to eventually demonstrate the efficacy in human trials and make our product commercially available, but at the moment we are in the early stages of the whole process.”
DNovo is not the only company working on lab-grown hair cells. Another biotech company, Stemson Therapeutics, received $15 million in funding in July to find a cure for hair loss with “with a novel cell regeneration technology using the patient’s own cells to generate new hair follicles.”
In 2006, Japanese researcher Dr. Shinya Yamanaka discovered a formula to convert any type of human tissue into stem cells. Since the discovery of so-called iPSCs, they have become the basis for many cutting-edge therapies.
Stemson Therapeutics is among them. The company claims that it is the first to “l(fā)everage an iPSC approach to treat hair loss by generating de novo hair follicles.” Its technology is not yet commercially available.
People who want more hair have long been able to get hair transplants. However,?the number of such transplant procedures is declining?as U.S. consumers switch to ingestible products and foams including Nutrafol?and Rogaine.
