公司會比電話你,你自己揀比定唔比,包血分2份,可以用2次.
如果你儲18年,但你在10年(for example)就用了,沒有東西再要儲,公司會把你余下儲的時間的費用退給你.

以下的都是我個sales話我聽的,其實你可以問下你接觸個sales.

我JOIN嗰間公司個血包是咁設計的,我唔知其他公司用的血包是不是也一樣,你可以問下你要JOIN嗰間公司個SALES.

佢只係可以分兩次呀? 分多幾包,得唔得架?

以現時既科技，臍帶血根本唔夠一個成人用
遑論用兩次

yes, for clinical use..

但係research use.. 有d試過做expansion都可以
而個blood bag有兩個部份, 細嗰邊係design for expansion架!

cord blood stem cell 經過expansion後能否保留其stem cell的primitive狀態，能否依然能differentiate成治療各種疾病所需要的各式細胞，尚在研究中。外國clinical trials有成功個案，但目前依然係要每種病去試，而且大部份reports依然係要expanded stem cells + certain amount of stem cells去做，只用expanded cord blood stem cells for treatment in human，全球今年年初先有第一篇成功既report 。香港既cord blood stem cell 既research 同clinical study尚在起步，目前香港冇report 過successful use of expanded stem cells in humans, 更無私人實驗室提供cord blood stem cells expansion service (請有咁專門既知識既scientist，再set up一個實驗室去提供一個咁少人用既服務，一定好貴；如果到時BB大個左唔好彩有病但都仲未有咁既service，咁拎住一人份既cord blood都得物無所用）

保留臍帶血，相信各位父母都只係抱住買個保險既心態。但我就我所見，現時各間保留臍帶血公司既銷售手法都好有問題。有D sales同人講留左一個孩子既cord blood，其他兄弟姐妹甚至父母都用得（實情係同organ transplant類似，有match有唔match，只係cord blood stem cells match既要求比一般器官移植低）。而且D公司只會講現時有咩研究用到cord blood stem cells, 卻避提那些研究所需stem cells份量及是否autologus (本人的）stem cells，有D仲連animal studies都拎黎講。The European Group on Ethics in Science and New Technologies advised the European Commission that "The legitimacy of commercial cord blood banks for autologous [self] use should be questioned as they sell a service, which has presently, no real use regarding therapeutic options. Thus, they promise more than they can deliver. The activities of such banks raise serious ethical criticisms." The American Academy of Pediatrics美國小兒科醫學會 policy also states that "private storage of cord blood as 'biological insurance' is unwise" unless there is a family member with a current or potential need to undergo a stem cell transplantation. 現時o係外國，各政府及醫療官方機
構鼓勵既係public cord blood bank，因為配對cord blood既要求比一般organ transplant低，加上捐出臍帶血唔會帶來傷害，願意捐出既人自然比器官、骨髓捐贈者多，那麼有需要人士在public cord blood bank找到配合樣本的機會自然大增，而且可以攞到多於一份cord blood stem cells用於治療，比起private bank只能access自己既一份cord blood，實用性自然大大提高。美國public bank容許市民以低價儲起臍帶血，供本人及公眾使用，而本人有更高priority去使用那一份血。可惜香港這方面既宣傳同執行都唔夠徹底，紅十字會只在有限醫院在有限時段收集捐贈者既臍帶血，個public bank就唔大。奢求從private bank得到臍帶血唔實際，人地俾左幾萬蚊去儲又點會輕易捐出黎。結果就係一班用唔著（或就算用得著都唔夠stem cells去用）既人儲起一堆stem cells，真正有需要既人就得唔到。

有餘錢的話，留起BB既臍帶血都冇壞既，畢竟冇人知幾十年後科研會發展成點。但同時相對地，到時既科研相信已經可以將一般細胞轉化成stem cells（呢類研究外國一直進行中，初步已有成功例子）。我打咁大篇野，係想俾各位媽媽知，現時科技、香港既科研條件同實際執行上，都未做到各間臍帶血公司sell既好處。D公司既銷售手法同香港政府對呢類公司欠缺監管，都好有問題。佢地提供了一個美好願景，但對如何實行隻字不提，亦唔會「理得你咁多」。

I expect the telomere would be getting shorter and shorter in such case.. what's the point to have a short life-span stem cells?

stem cell has telomerase, which can extend telomere.

Most of the cells in the patients have shorter telomere according to their age
Would you think that the use of stem cells with telomere as long as those in infants can give you a longer life-span? If not, what's wrong to use induced pluripotent (i.e. reprogrammed) stem cells derived from the patients' own cells? Their telomeres would have the same length as those in other normal cells in the patients' body.
My point is, the research of reprogramming of "normal cells" back to pluripotent stem cells is on-going and robust in other countries. If one has to wait for the development of a successful and reliable protocol for expansion of cord blood stem cells while retaining its pluripotent properties so that one's own cord blood stem cells stored would be really usable, the reprogramming technology is also catching up at the same time.

However, that's still not my main concern.
What bothers me is that there's no laboratory undergoing the "expansion service" in HK and there's no reported clinical use of one's own privately stored cord blood stem cells for treatment. Those companies just store the cells and tell the expecting parents that cord blood stem cells have novel, miracle functions, but they never promise help arranging hospitals and laboratories for research and treatment when the client really needs it. If the patient really needs the cells and he/she manages to find a private laboratory/private hospital for arranging stem cell expansion, that would cost at least dozens of thousands (for the expertise, apparatus and reagents). And I doubt if it can be covered by medical insurance or the public hospitals can provide this kind of service (unless the patient's case is regarded a clinical case for research and study, then the medical fee would be one tenth of the original price).

我去cryolife 個site 度睇佢介紹,d 器材o下o下都以百萬計,睇度佢地好專業呀,有專人運送比客戶,係世界各地`都運送,hk公營好似唔會甘去投資.

數以百萬對一間private life science lab而言只係小數目，如果冇就嚇親人啦。
運左俾個客之後又點？又咪係要個客自己去搵scientist、醫生做實驗同治療。有冇private lab去做呢？store cord blood stem cells, 任何產婦都可以做，客源咁大個價當然可以壓低。但真係要拎D cells 去做expansion or other experiments for treatment, 可能連當中百份之一既人都冇，但當中需要既expertise, equipment, reagents絕對遠遠高過單單係儲存臍帶血，個cost可想而知。

may be they just cannot promise, but they can try their best to arrange it.
as what they did in 1-2 individual case(s) which I heard.

btw, thx for your info.
