視網(wǎng)膜色素變性的細(xì)胞療法尚需進(jìn)一步改良才能應(yīng)用于人類。與傳統(tǒng)培養(yǎng)方法不同，我們的新技術(shù)可產(chǎn)生一層密集的視桿細(xì)胞，適于進(jìn)行移植，但移植了這種細(xì)胞層之后，還需用其他關(guān)鍵手段來提高視力。光感受器細(xì)胞不同于簡(jiǎn)單的上皮支撐組織，需要整合到眼睛的神經(jīng)回路中;尤其重要的是，光感受器需與另一種感覺細(xì)胞——雙極細(xì)胞——重新形成細(xì)胞連接，而我們尚不知道如何有效形成這種連接。若能成功移植光感受器細(xì)胞，將有望使視網(wǎng)膜色素變性患者至少恢復(fù)部分視力，甚至使晚期患者受益。
青光眼也許是這三種疾病中zui難用細(xì)胞療法治療的。胚胎干細(xì)胞培養(yǎng)固然能夠產(chǎn)生這種療法所需的神經(jīng)節(jié)細(xì)胞，但胎兒出生后，視神經(jīng)的再生長(zhǎng)便會(huì)受到抑制。神經(jīng)節(jié)細(xì)胞發(fā)出分支，形成視神經(jīng)，向大腦傳遞信號(hào)，這些分支稱作軸突;迄今為止，人們還沒有發(fā)現(xiàn)誘導(dǎo)其軸突與其他細(xì)胞重新連接的方法。
比起現(xiàn)有的組織工程學(xué)技術(shù)，即將細(xì)胞安放到皮膚或膀胱形狀的骨架上，胚胎干細(xì)胞分化成的組織顯然要好得多。作為研究者，我們必須謹(jǐn)慎而有耐心地揭示發(fā)育中的細(xì)胞所隱藏的奧秘——由單個(gè)細(xì)胞形成眼睛這樣的復(fù)雜器官，究竟經(jīng)歷了怎樣復(fù)雜的過程。
在懷孕期間，新的抗原抗體干細(xì)胞群產(chǎn)生，與那些參與非抗原抗體的發(fā)育和維持的不同，這些干細(xì)胞重塑乳房及在哺乳期間分泌乳汁喂養(yǎng)新生兒。通常情況下，這些干細(xì)胞不僅有助于早期重塑事件，而且在乳汁開始生產(chǎn)時(shí)關(guān)閉。
然而，加州大學(xué)圣地亞哥分校醫(yī)學(xué)院和穆爾斯癌癥中心的研究人員發(fā)現(xiàn)，調(diào)節(jié)抗原抗體期間的干細(xì)胞活化的信號(hào)被癌細(xì)胞劫持，用來生產(chǎn)快速增長(zhǎng)，更具侵略性的腫瘤。相關(guān)文章發(fā)表于2014年8月11日的《Developmental Cell》雜志上。

抗原抗體與抗原抗體癌之間的早已知道，但抗原抗體和抗原抗體癌風(fēng)險(xiǎn)之間的關(guān)系卻很復(fù)雜。雖然有一個(gè)孩子會(huì)降低婦女在以后生活中患抗原抗體癌的風(fēng)險(xiǎn)，但是，每次抗原抗體后都會(huì)有一個(gè)抗原抗體癌的高侵襲性形式發(fā)展的短期風(fēng)險(xiǎn)增加。目前的研究表明，懷孕期間，影響干細(xì)胞行為的重要分子可能促進(jìn)了這些與抗原抗體相關(guān)的更具侵襲性抗原抗體癌的發(fā)展，研究人員計(jì)劃進(jìn)一步研究這一種可能性。

Retinal pigmentosa cell therapy needs further improvement can be applied to humans. Unlike traditional methods of culturing, our new technology produces a dense layer of rod-like cells that are suitable for transplantation, but after transplanting this layer of cells, other critical tools are needed to improve vision. Photoreceptor cells, unlike simple epithelial support tissues, need to integrate into the neural circuitry of the eye; in particular, photoreceptors need to be reconnected with another sensorial cell, the bipolar cells, and we are not yet Know how to effectively form this connection. Successful transplantation of photoreceptor cells will hopefully allow at least partial visual acuity recovery in patients with retinitis pigmentosa and may even benefit advanced patients.
Glaucoma may be the most difficult of these three diseases to be treated with cell therapy. Although embryonic stem cell culture can produce the ganglion cells needed for this therapy, the growth of the optic nerve is inhibited after the birth of the fetus. Ganglion cells branch to form optic nerves and send signals to the brain. These branches are called axons; to date, no method has been found to induce their axons to reconnect with other cells.
It is clearly much better to differentiate embryonic stem cells into tissue than existing tissue engineering techniques, where cells are placed on the skeleton of the skin or bladder. As researchers, we must be careful and patiently revealing the hidden secrets of developing cells - the complex processes experienced by a single cell forming a complex organ such as the eye.
During pregnancy, new populations of antigen-presenting stem cells are produced that, unlike those involved in the development and maintenance of non-antigenic antibodies, reshape the breasts and milk during lactation to feed newborns. Often, these stem cells not only help in early remodeling events, but also shut down when milk begins to be produced.
However, researchers at the University of California San Diego School of Medicine and the Moores Cancer Center found that signals that regulate stem cell activation during antigen-antibody abstraction were hijacked by cancer cells to produce rapidly-growing, more aggressive tumors. Related article was published in Developmental Cell magazine on August 11, 2014.
Cell Subcategory: Mechanisms of Proliferation of Cancer Cells Hijacking Antigen-derived Antibody Stem Cells
The link between antigen and antigen-antibody cancers has long been known, but the relationship between antigen-antibody and antigen-antibody cancer risk is complex. Although having one child reduces the risk of developing anti-cancer antibodies in later life, there is an increased short-term risk of development of a highly aggressive form of antigen-antibody cancer after each antigen-antibody. Current research shows that important molecules that influence stem cell behavior during pregnancy may contribute to the development of more aggressive antigen-antibody cancers associated with antigen antibodies, and the researchers plan to investigate this possibility further.
